The first stream of economic studies on public policy responses during the COVID-19 pandemic focused on the stringency, the effectiveness, and the impact of the countries’ interventions and paid rather little attention to the corresponding means used to support them. The present paper scrutinizes the lockdown measures and, particularly, examines the optimality of the lockdown fines imposed by countries worldwide towards ensuring citizens’ compliance. Initially, a triad of fine stringency indicators are compiled, and the stringency of fines is evaluated in a comparative context, among the countries considered. Consequently, the fine stringency is incorporated into a regression analysis with various epidemiological, socioeconomic, and policy factors to reveal any drivers of fine variability. Finally, theoretical approaches behind fine optimality are capitalized and real data are used towards estimating the optimal fine for each country considered. The objectives of the paper are, first, to check for any drivers of fine stringency around the world and, second, to develop and test a formula that could be used in order to assist policy makers to formulate evidence-based fines for confronting the pandemic. The findings of the paper highlight that fines do not seem to have been imposed with any sound economic reasoning and the majority of countries considered imposed larger real fines, compared to the optimal ones, to support the lockdowns. The paper stresses the need for the imposition of science-based fines that reflect the social cost of non-compliance with the lockdown measures.

Policy-led interventions in the tourism domain should acknowledge the particular challenges of the territories to be implemented to promote desirable impacts. When intervention areas exceed the national level, the indicator approach may prove effective in determining the particular needs of different areas, thus better identifying projects that could bring the most change to lagging areas. The present study tests the potential of indicators to drive spatially targeted policies by proposing and implementing a methodological framework that examines whether the activities of selected projects under the 1st call of the Interreg-MED Thematic Objective of Sustainable Tourism effectively covered the needs of the Mediterranean regions. Furthermore, it builds regional clusters as a means to prioritize future interventions in the most suitable regions, in consideration of their particular weaknesses. The analysis revealed that interventions could have been more effectively allocated, and that more active participation of Mediterranean regions is needed. The proposed framework could serve as a starting point for enhancing the evaluation processes for project selection and lead to improvements in the policy framework for sustainable tourism.

This paper seeks to underline the driving factors of farmers’ engagement in Participatory Research Projects (PRPs). This is a critical issue for formulating efficient and effective technology transfer channels, essential for improving the operational status of agricultural holdings. A survey was conducted on a sample of 326 Greek arable crops farmers. An explanatory framework consisting of three major factor categories and 11 variables was developed. A logistic regression analysis empirically tests the effect of the variables on the participation of farmers in PRP. Furthermore, the relative importance of variables and factors is extracted with the Shapley–Owen decomposition analysis. The results show that Farmers’ Willingness and Social Influences are the factors that mostly affect their decision to engage in a PRP. The farmers’ ability consisting of socioeconomic and demographic variables has a small effect on their decision-making process. The estimated effects can help decision-makers to shape and prioritize more targeted policies for farmers’ engagement in research. Additionally, this paper sets the basis for shifting research from simple estimations of the effect of variables on farmers’ decision-making, to a more comprehensive estimation that also accounts for the strength of these relationships. The paper fills a gap in the literature of studies on farmers’ decisions for participating in PRPs, by developing and testing an explanatory framework which also accounts for the relative importance of each factor/variable.

Daylight utilization significantly contributes to energy savings in office buildings. However, daylight integration requires careful design so as to include variations in daylight availability and maintain a balance between factors such as lighting quality and heat gain or loss. Designers with proper planning can not only improve the visual environment and create higher-quality spaces, but simultaneously minimize energy costs for buildings. The utilization of photosensors can exploit the benefits of daylighting by dimming the lighting system, so that no excessive luminous flux is produced, thus leading to energy savings as well as visual contentment. However, the human factor is crucial for the proper function of a lighting control system. Without its acceptance from the users, energy savings can be minimized or even negligible. The objective of this paper is to present a post-occupancy evaluation regarding occupant satisfaction and acceptance in relation to daylighting in offices equipped with automated daylight controls. In addition, the response of the users was compared with lighting measurements that were performed during the post-occupancy evaluation. Three case studies of office buildings with installed daylight-harvesting systems were examined. The age of the occupants was a crucial factor concerning their satisfaction in relation to the lighting levels. Aged users were more comfortable with lighting levels over 500lx, while young users were satisfied with 300lx. The impact of different control algorithms was outlined, with the integral reset algorithm performing poorly. The acceptance of the users for the closed loop systems maintained the expected energy savings of the daylight harvesting technique. Most of the occupants preferred to use daylight as a light source combined with artificial light but having the control to either override or switch it on and off at will. The results shown that a post-occupancy survey along with lighting measurements are significant for making an office environment a humancentric one.

The mitigation of spatiotemporal pressure is directly related to improvements for the competitive positions of coastal tourist destinations. Extensive diversification initiatives have been undertaken in many regions in order to achieve this goal. Despite the importance of specific spatiotemporal features of tourism, they have yet to be adequately integrated into existing studies that evaluate the comparative performance of destinations. To fill this gap, this paper uses a non-parametric data envelopment analysis method and builds a synthetic index of spatiotemporal efficiency in order to evaluate the performance of 37 Mediterranean coastal regions. In addition, it uses a bootstrapped truncated regression model to test the effects of product and spatial diversification on the spatiotemporal performance of destinations. The results suggest that both product and spatial diversification may enhance the spatiotemporal efficiency of destinations. Finally, they demonstrate that the easing of spatiotemporal pressures bears a real cost in terms of lost overnight stays that vary across different Mediterranean destinations based on unique local factors.

This paper assesses the comparative performance of the Mediterranean coastal destinations using data envelopment analysis, considering both the efficiency and effectiveness dimensions. The analysis does not only provide a benchmarking framework for the destinations, but a framework to reveal, in a comparative context, the trade-offs between efficiency and effectiveness, the sources of inefficiency, and the pillars of effectiveness, for each region. This paper advances the current literature in destination performance benchmarking, under the production frontier method, by incorporating the effectiveness dimension to the broadly used efficiency consideration. This advancement is of critical importance, considering that the results of this paper support the lack of a strong relationship between destinations' efficiency and effectiveness. Therefore, individual destinations' assessments, based only on one of the two performance dimensions, may lead to biased estimations that may mislead policy interventions.

Sustainable tourism development is considered an essential challenge for improving resource management in coastal and maritime areas. In this context, various initiatives have been developed for facilitating the assessment and monitoring of tourism sustainability. Nevertheless, the perception of sustainability varies across different tourism stakeholders, since they approach tourism development under different perspectives while the issue of data availability has been a great barrier in measuring sustainability. The present paper examines the perceptions of sustainability observed over a Community of projects with the common aim of enhancing coastal and maritime tourism sustainability at the Mediterranean. Based on surveys, the Community of projects conceptualizes sustainability, reveals their own strategies in operationalizing sustainability assessment and evaluates the usefulness and the main gaps of various sustainability assessment toolkits. The findings of the study signify that tourism sustainability is a broad concept allowing for different interpretations. The assessment of sustainability seems to be affected by the perception and weight attributed to the economic, social, environmental, and governance pillar of sustainability by each project. Finally, the applicability of international assessment toolkits could be questioned as these do not reflect the objectives of the projects and tailored made approaches are considered as essential for operationalizing sustainability assessments.

This paper builds on the knowledge generated by the past studies on agricultural convergence and extends it in order to provide a more holistic analysis in geographical terms, and a more detailed analysis of the aspects that shape the overall performance of the countries. The paper adopts a global scale of analysis and assesses convergence in terms of value generation, energy efficiency, and technical efficiency. To do so, analysis is based on a series of regression models in order to examine if the policy changes that occurred in the beginning of the 1990s promoted the convergence of the agricultural sector’s performance across the globe. Two main types of convergence were tested. The first refers to the σ-convergence and the second type is this of β-convergence. The lack of any type of convergence regarding the generated value across countries around the globe has shown that the liberalization of the market has not brought about any substantial improvements in the position of the weakest countries. On the other side, a convergence of both σ and β type has been found for the energy efficiency of the countries. That is, it resulted in improvements in their energy efficiency. Policy changes of the early 1990s have substantially improved the position of the weakest countries. There was also a positive effect on the productivity of vegetable cultivations whilst it seems that they have slowed down a strong convergence process for fruit productivity.

Office lighting planners are faced with two key objectives as their plans should meet customers’ needs and also be compliant with a range of policy guidelines targeted on a wide variety of lighting attributes. In the EU, the most recent relevant guidelines are led by the "2030 climate & energy framework" which among other targets calls for a more energy efficient office lighting planning. The new guidelines foresee stricter energy standards and therefore add to the complexity of the lighting planning task since they notably reduce the number of available luminaires, at least in the short-run. Although important for the industry, a thorough examination of current and forthcoming policies impact on the market of luminaires has yet to be conducted in a European context. The present paper seeks to cover this lack in the relevant literature by focusing in a European country, namely this of Greece, in order to capture the effects of various European and national policy guidelines in the market of luminaires. In order to enhance the validity of results a total number of 9,609 office luminaires available to the European market were selected. After controlling for any data misspecifications an extended statistical analysis was conducted in order to extract the composition of the market taking into account technical characteristics as the type and purpose of use of each luminaire, their luminous efficacy, their color temperature and color rendering index and some other attributes that affect luminaires’ compliance level with the policy guidelines but also their adequacy for being included in an effective lighting plan. The method employed by the present paper is expected to support future policy making as it adds a sound quantitative basis for examining any policy impacts but also the lighting planners to understand the current state but also the future trends of the market and adjust accordingly their future luminaires selections. The luminous efficacy analysis has shown that about 48% of the current office luminaires fail to pass the 85 lm/W threshold being set by EU. Only 5% and 13% of the luminaires can be used for general lighting and task lighting correspondingly for an energy efficient lighting design without resulting in a larger number of luminaires than it is needed.

Geography is an integral part of the cruise industry since cruises are conducted in the geographical space and thus are submitted to spatial and geomorphological constraints. However, the cruise-literature lacks of research focusing on the geographical aspect of the interactions existing between ports and cruise companies. This paper attempts to fill this gap by examining the spatial networks of two contemporary cruise companies operating in the Mediterranean, using complex network analysis that has been extensively applied to other shipping sectors, such as to the container liner shipping, but not, in a comprehensive context, in the cruise industry. The complex network analysis applied in this paper provides insights about the operational and geographical dynamics of the ports participating in the Mediterranean cruise network, which can help the cruise companies and the port authorities to comprehend and to measure their competitive position in the network. The overall approach develops a novel classification of ports according to their integration in the cruise network, an optimized modularity segmentation of the Mediterranean market by considering both operational and geographical aspects of this network, and an in-depth efficiency comparison between the spatial networks of the cruise companies.

The production of olives and olive oil in the Mediterranean region is one of the most important cultivations. The continuous changes imposed by the European Common Agricultural Policy (CAP) towards strengthening the influence of market forces have increased the necessity for the assessment of the efficiency of production protocols or patterns being implemented by the farmers. As regards olive trees cultivation, the efficiency of inputs utilization has not been studied in depth, despite the fact that this is a critical issue for both farmers and consumers. This study evaluates the efficiency rates of 100 Greek agricultural holdings specialized on olive trees cultivation by implementing a Data Envelopment Analysis (DEA) input oriented model. The inputs being used are land, fertilizers, agrochemicals, labour, and energy. The output being used is the revenue of each holding. The results quantify the significant variations of efficiency scores, providing evidence that there is space for restructuring the production process, in order to improve efficiency and thus decrease the production cost of inefficient farmers.

Studies on agricultural production practices advance within international literature and new methods are proposed in order to assess the agricultural sustainability, either at farm or macro level. The present paper builds on these advancements and develops a synthetic Eco-(in)efficiency index by employing a directional distance function—data envelopment analysis (DEA) model. This index is used in order to assess the sustainability of the EU agricultural sector for the period 1999–2012 on a country level. Furthermore, Eco-(in)efficiency, together with the energy use and greenhouse gas (GHG) emissions are regressed on the gross domestic product (GDP) of EU countries, in order to check for any environmental Kuznets curve relationship existence. Results signify that efficiency improvements are possible, both towards output development and GHG emissions reduction. In addition, the potential of each country in adopting more sustainable production practices is not totally connected with its economic development, as Eco-(in)efficiency and GDP levels of EU countries seem to be linked with an N-Shaped curve.

This paper aims to evaluate the impact of the ongoing economic crisis in Greece on alcohol consumption and binge drinking. For this reason, the Theory of Planned Behavior is being applied by using a sample of nearly 900 questionnaires. The questionnaire consists of parts trying to identify the attitude of the interviewees towards alcohol, their subjective norms of social environment, and the perceived behavioral control. This research has been implemented on a national level. The most important finding is the considerable difference in alcohol consumption compared with other countries faced similar negative economic situations. Drinking is considered as a source of pleasure and socializing. The participants’ perception is that family environment and friends are not considering drinking as a non-desirable way of entertainment. As one of the major results of the survey, drinking was found to not be driven by a necessity to overcome problems related to it, which is the main difference with previous studies in others countries, like Argentina, Russia, USA, etc.

Purpose The significant benefits associated with cruise tourism have mobilized port industry, as progressively, a large number of ports are developing cruise operations. Although increasing cruise traffic is a major goal for cruise ports, homeporting constitutes a strategic target of the majority of ports due to its greater economic benefits for both the port itself and its hinterland. The establishment of homeport traffic in a cruise port is subjected to a variety of port internal and external factors. Taking these into account, the paper aims at defining elements that affect the potential of a cruise port to become a homeport. Design/methodology/approach A sample of 47 Mediterranean ports is selected to form the basis for the implementation of an ordinal regression model which links the likelihood of ports to attract homeport traffic with seven explanatory variables which emerged from relevant literature and are split in the main categories of ports’ and hinterlands’ characteristics. To fit the model into the paper’s data, ports are divided into three categories based on their homeport cruise traffic. Findings The results of the empirical model signify that both internal and external factors affect the potential of a port to become a cruise homeport. Concerning the internal factors, adequate infrastructure allowing the facilitation of the last generation of cruise ships and the presence of a private enterprise in ports’ operation seems to foster homeport traffic. Additionally, efficiency in operations seems to be a crucial element. On the other hand, the connectivity of port’s; hinterlands, tourist infrastructure and the level of economic growth are proved to be the hinterlands’ elements which increase the likelihood of a port to attract additional homeport traffic. Practical implications The model forms a comprehensive evaluation basis for whether a cruise port should intensify its pursuit of homeport traffic, as the estimated coefficients could support port and local authorities to understand their competitive position against other ports and spot their strengths and weaknesses. Originality/value The paper contributes in the research dealing with the identification of crucial elements of homeporting from the port’s point of view. Although, it should be mentioned that previous efforts targeting on revealing the characteristics affecting the homeporting potential of ports mostly have been based on questionnaires and expert judgements or empirical models in which the total – and not the homeport traffic – was used as the dependent variable. With the proposed empirical model, home-porting choice analysis is transferred, on the one hand, from the stated preferences level to the revealed preferences level and, on the other hand, from an indirect to a direct approximation of the issue.

The aim of this paper is to examine the changes on food consumption patterns of households, following an economic crisis and recession. This paper identifies objective and subjective factors influencing consumers to purchase, or not, traditional and localised food. Furthermore, an impact assessment based on environmental and social criteria for food selection, like locality of production and healthy nutrition habits is conducted. Quite enlightening is the research on the spatial basis. The results of this approach signify the different consumption trends dominating the urban, semi-urban, and rural areas. There are also some implications for marketing and public policy makers to further strengthen consumption of traditional and locally produced foodstuffs, such as promotion of their nutritional characteristics, support of local economies, encouragement for adoption of healthy eating by children, as well as enjoyment of cooking.
