Having in mind the main debate “grease the wheels” vs. “sand the wheels”, the main objective of this study is to find the way in which corruption and shadow economy influence economic and sustainable development. A large cross-country database of 185 countries is used for the 2005–2015 time period. We find that corruption and shadow economy are poverty-driven diseases and they highly characterize low-income countries. Thus, the higher levels of corruption and shadow economy are correlated with low levels of economic and sustainable development. Then, the main contribution of this work consists of finding general and empirical evidence for the destructive role held by the corruption and shadow economy phenomena upon the economic and sustainable development of states. However, we also find some evidence that corruption can be also seen as a way to circumvent the law in order to achieve higher economic benefits and thereby to increase economic development. In addition, we find that economic and sustainable development in high-income countries is more strongly and negatively affected by the phenomena of corruption and shadow economy than in the case of low-income countries. Our research may have political implications for the government institutions that need to adopt the best-required policies, in order to boost economic and sustainable development. For low-income countries, we find some evidence for positive effects of corruption and shadow economy upon economic and sustainable development and the immediate practical implications are not to encourage but to effectively and strongly fight against these destructive phenomena and to find the proper channels to increase the institutional quality and to adopt the appropriate regulatory policies.

The COVID-19 pandemic has disrupted every facet of life globally. Business and commerce are key areas where the monetary crunch has been acutely felt. This study aims to analyze the various key changes in entities’ activities to evaluate the level of business performance in response to the COVID-19 pandemic. For this purpose, we use panel data analysis on 218 Romanian listed companies of different sizes (big and small) and belonging to different business sectors for the period June 30, 2019–June 30, 2020. We find that the net profits of the overall market decreased by 37.43% over the analyzed period. However, small companies engaged in agriculture, commerce, construction, IT R&D, and transport and storage witnessed better financial performance. In addition, our results show that equity financing, proper liquidity management, and an increased company size consolidate the economic performance of entities regarding return on equity and return on assets. Our findings are useful for policymakers such as managers and investors and can help them make the best decision for their managing or investing activities. Moreover, governments need to know how companies respond to the pandemic to identify the sectors of activity that are more vulnerable to the crisis’ effects and the main financial management decisions that must be adopted by companies during times of crises.

This study investigates correlations between board characteristics and firm performances. For this purpose, six board characteristics were chosen: (1) equilibrium between non-executive and executive members of the board of directors; (2) independence of board members; (3) selection of board members by the assistant role of the Nomination Committee; (4) training the members’ competences; (5) remuneration policy of board members by the assistant role of the Remuneration Committee; (6) improuving the accountability and transparency of financial information by the assistant role of the Audit Committee. The financial performances are represented by Return on assets (ROA) and Tobin’s Q. The present study sample consists of 55 Romanian non-financial companies which are listed on the Bucharest Stock Exchange (BSE) in 2012. We found the following characteristics in the majority of boards of directors: equilibrium between non-executive and executive members, independence of the members and concerns on training competences. On the other hand, the majority of companies do not have, within their governance system, advisory committees (such as Nomination, Remuneration or Audit Committees), which are meant to help the board in its decision-making. No statistically significant association was found between any of the board characteristics and performances represented either by Tobin’s Q or ROA, but the findings are in line with numerous studies conducted in developing countries and may be explained by various shortcomings which characterise the lagging of transition economies.

This study was carried out to empirically investigate the relationships between corruption and shadow economy among the European Union countries, over the period 2005-2014. Moreover, since one would expect corruption and shadow economy to be more common in poorer countries, this study was therefore carried out to determine how corruption and shadow economy affect economic development. The empirical findings of this study confirm a high and positive relationship between corruption and shadow economy, therefore a higher level of corruption involves a higher level of shadow economy. Regarding the influence of corruption and shadow economy on economic growth, a high and negative relationship was found. This means that increasing corruption and shadow economy negatively affects economic growth.
