The COVID-19 pandemic created an enormous disruption to the everyday life of the modern society. Among the various urban systems, transportation services were among those that suffered the most significant impacts, particularly severe in the case of highways. This paper addresses the challenges and responses to the pandemic from a private highway operator’s perspective and from a multidisciplinary perspective. Highway operators faced two main challenges: on one hand, the need to cope with the potential disruption caused by the pandemic and a national lockdown for almost three months, the provision of road services, and the requirement to ensure the proper operation and maintenance, and on the other hand, the strong negative impact of the pandemic on levels of traffic. Our case study shows that the operator’s management response in question is essentially characterised by being a first response to short term impacts while balancing for workers health and safety, engineering and management, internal business management, and overall economic impact. Highway operators were hardly prepared for such an event and became more focused on prioritising their employees and clients’ safety to avoid service disruption. Regarding levels of traffic, the pandemic has had severe effects, although to a varying degree, depending on the different types of vehicles (heavy, light, passenger, freight, among other types of vehicles) and the location of highways (coastal vs. interior). The lessons learnt can be valuable in future disruptive events and for other highway concession operators.

Purpose The purpose of this study is to propose and test a model on the impact of diversity over performance using a Portuguese national wide comprehensively matched employee–employer dataset of small businesses. Design/methodology/approach The study uses structural equation modeling to analyze the relationships between variables. The study addresses the impact of top managers and employees' diversity on firm performance considering two dimensions of diversity: knowledge diversity and social diversity. Findings The study provides a clear understanding of how workforce diversity affects performance differently at the two hierarchical levels. Both employees' diversities have stronger relations to performance than the diversity of top managers. Results point out to idiosyncratic aspects of services firms' dynamics that should be further explored. Research limitations/implications The study presents some limitations, since it uses data from a single country and the dataset provides limited variables. Practical implications The study offers evidence on the effects of diversity in small businesses alerting managers to acknowledge such influence when recruiting, selecting and training. With regard to services firms, managers should pay close attention to negative impacts of diversity over performance. Originality/value Never before to the authors' knowledge the managers' level diversity and employees' level diversity (considering two dimensions each) effect on performance have been addressed in a single national wide study.

Cost deviations have long been a relevant research topic within the field of public works and infrastructure. The literature has attempted to evaluate the frequency of deviations and overruns and the magnitude of these deviations. This paper provides a unique overview of 175 transport projects in the United Kingdom (UK), covering a period from 1985 to 2018, using data from the National Audit Office. The aim is to evaluate the cost deviations and overruns in the UK and to identify the main determinants, with a focus on exogenous determinants (context-related) which have been neglected in the existing literature. The results confirm that transport projects show a tendency towards overruns, although there are significant differences between road projects (with an average deviation of 18%) and other types of transport projects (with an average deviation of 60%). The results show that an increase in government efficiency levels leads to a decrease in cost overruns. This paper findings support the theory of Flybvjerg et al. (2018) that there is evidence of the existence of political determinants in cost overruns, but also that economic dynamics play a role in explaining cost overruns. Whether the political bias is psychologically or strategically-driven is yet to be demonstrated.

Over the past decades, there has been a trend towards privatisation in Europe. However, surprisingly little has been published in the finance literature on the industry effects of privatisation on non-financial firms’ capital structure. Talberg, Winge, Frydenberg, and Westgaard (2008) demonstrate that capital structures are industry-specific, and the literature on privatisation and leverage claims both a positive and a negative effect. Using a large sample of privatised firms in Europe, this paper analyses the impact of privatisation on firms’ capital structure. Our results provide no evidence that privatisation impacts firms’ capital structure. Instead, the level of leverage remains largely the same a few years after privatisation. These results remain unchanged even after controlling for certain characteristics, such as the type (asset sale or share issue) of privatisation and the percentage of privatisation. However, additional tests reveal that industry specificities are relevant in explaining capital structure variations following privatisation. When considering industry-specific characteristics, we found substantial statistical evidence that firms in capital-intensive industries experience a greater leverage level after being privatised. Our findings also suggest that governments may optimise privatisation processes after considering what capital-intensive firms may require in terms of funding long-term assets.

Public-Private Partnerships (PPPs) are frequently renegotiated as their contracts are long-term, often with a duration exceeding 30 years, involve major investments, and are necessary incomplete. Still, while contract incompleteness is difficult to prevent, renegotiation frequency does not decline in spite of decades of experience. Electoral cycles and political connections lead to strategic behaviour by both the public sector, intending to please the electorate, and the private entity, often taking advantage of the fact that the government cannot afford disruption in public services prior to elections. The bargaining power is held mainly by private firms/corporate consortiums who extract additional rents to compensate for underbidding at the initial bidding rounds. When a consortium dominated by a foreign firm, the frequency of negotiations is higher but the extraction of rents from renegotiations is lower, reflecting a lower degree of political connectedness. Experience with PPP projects does not reduce the likelihood of subsequent renegotiations. In spite of the recommendations of the PPP supervisor (the Court of Audit), the public sector has not implemented improvements in contract design and renegotiations clauses of PPP contracts.

This study explores how the stock market reacts to the award of highway concessions using the case of Portugal, a country which awarded 19 highway concessions over the period of 1998 to 2009. We focus on the abnormal returns of both the winning and losing publicly-listed companies that participated in all the tender processes, either individually or in a consortium. The results indicate a positive market reaction, although only for firms that have previously won a highway concession. Based on their experience in winning and operating highway concessions in Portugal, these firms can bid more effectively and present proposals which generate a better value proposition for their shareholders. Accordingly, investors immediately gain from the benefits of the forecast experience and the synergetic gains from operating more than one highway concession. On the opposite, markets react sceptically when the firm starts to operate a highway concession in Portugal. This paper also suggests that markets reward more lengthy contracts positively, as well as if the biding company is not headquartered in the country.

Sustainability has become a significant issue for firms and investors throughout the world, although it cannot be attained if policies impact the stability of firms’ dividend policies. In this paper, we use data from the Stoxx Euro 600 firms from 2000 to 2019 and the ESG (environmental, social and governance) scores from Thomson Reuters to assess the relationship between ESG responsibility performances and the firm’s dividend policy. The results indicate that more sustainable firms exhibit a more stable dividend payout. This result is also valid when the ESG pillars are analysed, specifically, the environmental and governance pillars. The findings further suggest that higher ESG scores reveal better long-term alignment with shareholders and other stakeholders due to more proportionally stable profit sharing.

Activist shareholders play an increasingly relevant role in management decisions, especially in their activities aimed to influence corporate decisions towards enhanced performance and profitability. However, the level of success of such strategies is not yet fully understood, as reported in the existing literature. Most of the literature has focused on performance, although other firms’ policies catch activist shareholders’ attention. A key strategic decision is precisely the dividend policy. In this paper, we assess the likelihood of a dividend payment and the time invariance of the dividend policy while controlling for firm-specific and market-specific effects. Our data cover the nonfinancial US-based firms targeted by activist shareholders in a large time span from 2000 to 2017. Taking both a quantitative econometric approach and a qualitative one (fsQCA), our findings support the claim that activist campaigns are positively associated with the likelihood of firms’ decisions to pay dividends, even if it occurs at the cost of higher volatility on the dividend level and payout ratio. Our findings also suggest that activist shareholders prefer to collect dividends in the years following the campaigns, arguably as a risk management mechanism.

This paper focuses on the interconnections between sovereign debt and the competitiveness of nations in the aftermath of the recent sovereign debt crises in the Eurozone. Further, it identifies new challenges to improving competitiveness. Based on a deductive approach, we analyse secondary data regarding sovereign debt and competitiveness in 28 EU countries for the period from 2006 to 2017. We also look at the recent theoretical developments in the competitiveness of companies, nations, and regions with the goal of identifying the new challenges to Portuguese competitiveness. In the period under analysis, Greece, Ireland, and Portugal had considerable losses in competitiveness and increases in their sovereign debt ratio. Despite benefiting directly from Porter’s insights into improving the country’s competitiveness, the Portuguese sovereign debt ratio has increased steeply. A previous analysis identified a path; however, there are new challenges such as those associated with EU competitiveness, shared value, and smart connected products. These need to be considered to support the creation of new strategies and policies for a small and open economy. Based on our analysis, we argue that competitiveness-oriented policies must more explicitly consider the negative implications of sovereign debt, and must recognize the new challenges to competitiveness.

There is a growing concern in the field of public administration regarding cost overruns, which are often perceived to be a sign of project failure. Past studies have identified potential causes and explanatory factors for the occurrence of cost deviations. This article expands the existing body of knowledge by explicitly considering exogenous determinants (political, governance, and economic) to analyze how public management affects cost deviations and overruns. The article provides an empirical analysis of 4,305 projects developed in Portugal from 1980 to 2014. The study found that electoral periods; institutional, legal, and regulatory frameworks; and economic cycles all influence cost overruns.

Urban mobility is experiencing a profound change. Mobility patterns are becoming more complex, and typical home–work–home travel is no longer the rule, as journeys tend to connect multiple points in a rather inconstant pattern. This has changed the approach to transport planning. Existing transportation planning and operation approaches have been focussed on the ability to identify and forecast typical home–work/school–home travel and subsequently plan the transport system accordingly. The traditional approach has been: Forecast - > plan - > deliver. New mobility patterns and mobility solutions are characterised by greater flexibility, taking advantage of the “sharing concept” and simultaneously providing solutions that have lower greenhouse gas (GHG) emissions. These dynamics and an evolving environment raise several new challenges at different levels, fostering the development of Mobility-as-a-Service (MaaS). This system transforms the physical transportation system into a commodity and takes advantage of the internet of things (IoT). However, the onset of MaaS solutions is anything but linear. Several business models have emerged, with different partners originating from different industries (e.g., technological, transport operators, infrastructure managers, etc.) developing their own solutions, often in competition with others. It is not unusual to find different MaaS solutions in the same city, which integrate different solutions. This paper intends to provide an analysis on the main challenges affecting mobility in general, and MaaS in particular, as well as the main business models used for delivering MaaS solutions. The paper uses a case study in Lisbon to illustrate some of the challenges.

Urban mobility is experiencing a profound change. On the one hand, mobility patterns are becoming more complex, and typical home-work-home travel is no longer the rule, as journeys now tend to connect multiple points in a rather inconstant pattern. This has changed the approach to transport planning, in that the existing transportation planning and operation approaches have been focussed on the ability to identify typical home-work/school-home travel and subsequently plan the transport system accordingly. The traditional approach has been: forecast -> plan -> deliver, as new mobility solutions are emerging. These are characterised by greater flexibility, in that they take advantage of the “sharing concept” and simultaneously provide solutions that have lower GHG emissions. Urban mobility follows a fuzzier pattern, with even the urban transportation system behaving like an active organism, where solutions are often quickly replaced. This dynamic and evolving environment raises several new challenges at different levels. The best digital solution system is the Mobility-as-a-Service (MaaS) one. This system transforms the physical transportation system into a commodity and takes advantage of the internet of things (IoT). However, the onset of MaaS solutions is anything but linear. Several business models have emerged, with different partners originating from different industries (e.g., technological, transport operators, infrastructure managers, etc.) developing their own solutions, often in competition with others. It is not unusual to find different MaaS solutions in the same city, which integrate different solutions.

What drives the dividend policy at the firm level? Literature has been mainly focused on taxes, type of shareholders and market effects. In this paper, we perform a novel approach to dividend policy literature. First, controlling for tax, market and shareholders effects, the paper intends to analyse which firm variables are more relevant on the decision to pay dividends, on the decision to pay regular dividends and on the decision of the amount of dividends. The paper uses non-financial firms listed on Euronext stock exchanges from 2000 to 2017, and we combined a quantitative econometric perspective with a qualitative, using fsQCA. We found that variables such as operating margins, analyst’s coverage and shares in free float have substantial impacts on the dividend policy of firms. Moreover, firm’s size is the major determinant of the dynamics of the dividend policy.

Along with an increase in the use of PPPs for the management and development of transport projects, considerable evidence exists regarding the difficulties encountered in creating robust contracts. It becomes necessary to adapt contracts to new circumstances, through renegotiation. The aim of this paper is to characterise this renegotiation and to improve the knowledge regarding what are the main drivers for renegotiation, and what are their main determinants and consequences. This paper focusses on the analysis and discussion of renegotiation in transport PPP projects, using a sample of seven projects in Brazil, during the period of 2006 to 2016, for a total of 20 renegotiations. The results exhibit a high frequency of renegotiation, and evidence of political influence on the likelihood of renegotiation, particularly when elections occur and/or there is a change in government. Institutional and regulatory framework play a key role in decreasing the likelihood (and consequences) of renegotiation.

There is a significant concern about cost deviations and overruns in public projects, particularly by the local governments. The magnitude of expenditure on these infrastructure projects justifies the search for cost deviation reasons, particularly cost overruns. The existing literature also identifies a tendency towards cost overruns in infrastructure projects. However, the analysis of cost overruns determinants has mostly focused on endogenous project characteristics. This research uses a dataset of 4,305 public infrastructure projects, of which 3,338 are local projects, carried out in Portugal between 1980 and 2012. Exogenous determinants (e.g. political, institutional and governance, and economic-related) are also considered in the analysis. An average cost overrun of 19% (9 billion Euros in volume, with a 1 billion Euros overrun) is identified. It is found that central governments incur on an average cost overrun of 23% and local governments on 6%. The analysis confirmed that projects developed by local governments tend to perform better regarding cost deviations and overruns and that exogenous determinants (particularly the political, institutional and governance environment ones) have a strong impact on cost deviations and overruns. These findings on exogenous factors can help local governments to make better management decisions, enhancing governance and institutional frameworks to improve the decision-making process when launching new infrastructure.

Several studies in the area of project management have concluded that development projects implemented by nongovernmental organizations (NGOs) have specific features associated with the diversity of stakeholders, the scarcity of resources, and the importance of intangible objectives. Consequently, classical methodologies may not be suitable. The purpose of this paper is to analyze the project management tools used by nongovernmental development organizations (NGDOs) and their effect on project performance. This was done by studying the perceptions of project managers from Portuguese NGDOs. A mixed methods design was adopted. In an initial phase, a questionnaire was sent to Portuguese NGDOs. The resulting data was analyzed by fuzzy-set qualitative comparative analysis (fsQCA). In a second phase, semi-structured interviews were conducted with a subgroup of selected project managers from these organizations. The results reveal a specific profile regarding the importance of project management tools and methodologies for NGDO performance. These results reflect the specific features of these types of projects and organizations.

The inaccuracy of traffic forecasts has long stood as a central research theme in the field of infrastructure and transportation studies. The literature presents several motives for this phenomenon, ranging from a political bias, insufficient technical preparation, changing urban patterns, and economic dynamics. Uncertainty due to the inaccuracy of forecasts can have a profound impact on the infrastructure development process, right through from the preliminary studies up until the operation and re-negotiation of contracts (in cases when projects are developed using a concessions model). This paper provides an extensive systematic review of forecast inaccuracy in roads and railways projects (analyzing trends, causes, and results). The research found that: (1) forecasts in rail projects are generally more optimistic than in road projects; (2) over the last couple of decades the accuracy of forecasts has not improved significantly, and; (3) there has been a generalized ramp-up effect in forecasts.

Cost deviations and overruns are a recurrent topic in the transport infrastructure literature. Even though there is a general trend towards a more frequent occurrence of overruns the main determinants of such phenomena are still not consensual. This paper analyses a dataset of 1091 transport projects developed by the Portuguese government (central, regional, and local) between 1980 and 2012. The methodology builds on existing approaches but provides a more ambitious (and innovate) approach towards the incorporation of exogenous determinants, examples being political, legal and regulatory, and economic ones. The analysis suggests that these exogenous variables that have been under-valuated in the existing literature, and that they do, indeed, play a relevant role in understanding cost deviations.

The role of regulation in infrastructure development has changed significantly over time. Changes have been carried out at different levels: institutional (changing entities), regulatory model (contractual regulation gaining momentum), and contractual changes (different risk allocation). This paper looks at the recent evolution in the Portuguese case for the regulatory institutional arrangement and models developed, in the rail, road, maritime, urban transport and airport sectors. Although there was a clarification of the role of the public and private sector over time, and the political acknowledgement of the importance of a stable and effective regulatory framework, there has been an unstable institutional scenario. Furthermore, the role of the regulators in Portugal is extremely limited, given the predominance of the contractual regulatory model, which thus decreases the level of flexibility needed to cope with the challenging adaptations driven by technology.
