This paper revisits Saccone’s (2020) analysis of the impact of economic freedom on decile income shares for a panel of developed and developing nations during 1980-2014. Saccone found that higher levels of economic freedom corresponded with lower income shares for the bottom 8 deciles and higher shares only for the top 2 deciles. Instead of decile income shares, this paper focuses on the impact of economic freedom on decile income levels. We find that the income per capita for all 10 deciles increases as economic freedom increases.

Recent literature on individual vs. group decision-making, in risky contexts, has brought about divergent results, mainly depending on the institutional rules through which groups take decisions. Some studies where group decisions relied on majority rule showed no appreciable difference between individuals and groups’ preferences, others where unanimity among group members was required found collective decisions to be less risk-averse than individual ones. We elicited groups’ preferences over risk using what we defined “endogenous-decision-rule”, i.e. leaving groups free to endogenously solve the potential disagreement among their members. Our results unambiguously show that individuals are more risk seeker than groups when facing gambles with positive expected payoff difference and more risk-averse in the opposite case.

We investigate the behaviour of retail diesel prices in Brazil using fractional integration, with weekly data from January 2010 to April 2020. In this period, we have 3 episodes of relevant economic implications in the country under analysis: i) impeachment of the Brazilian President;ii) the lorry-drivers' strike;iii) the rise of the global Covid-19 epidemic. We use a sliding windows approach to analyze price dynamics over time. The results suggest that, at the beginning of the sample, prices were non-stationary and non-mean reverting. Over the time, diesel prices become non-stationary with mean-reversion in Midwest, South and Southeast regions, while in the North and Northeast we cannot reject non-stationarity and non-mean reversion (d > 1). Results are relevant for market agents and policy-makers, as it can be inferred whether exogenous shocks are temporary, despite taking some time to dissipate completely.

We propose a dynamic, forward-looking hedging strategy to manage stock market risks via positions in REITs, conditional on the level of risk aversion. Our findings show that REITs do not only offer significant risk reduction for passive portfolios, but also offer much improved risk-adjusted returns with the greatest benefits observed for Australia, Canada and the U.S. Overall, our findings suggest that time-varying risk aversion can be utilized to (i) establish effective hedges against stock market risks via positions in REITS, and (ii) improve the risk-return profile of passive portfolios.

The objective of this study is to examine the impact of economic crisis on cost structure configuration of companies. For this reason, an empirical study in the form of online survey has been carried out in 82 Greek manufacturing companies. We received data from two periods of great economic recession, namely during fall of 2013 and spring of 2015. Results indicated that companies most affected by the economic crisis, replaced fixed costs with variable ones. Cost structure configuration is the “tool” that companies used to limit the consequences of the crisis in their profitability.

This study analyzes the corporate social responsibility (CSR) activities of the Korean chaebols to establish whether these firms engage in social duties and practice noblesse oblige. To measure the extent of the CSR activities, we use the index of the Korean Economic Justice Institute (KEJI) from 2005 to 2017. We find that the level of the CSR activity among chaebol firms with weak governance is low. Moreover, we show that chaebol firms with credit rating concerns reduce their CSR activities. Overall, our results indicate that Korean chaebols tend to neglect the CSR activities.

In this paper, we examine the effect of central bank transparency on inflation persistence, using panel data analysis. The existing literature has shown a significant impact of central bank transparency on macroeconomic variables, such as inflation, but not many efforts have been made about its effect on inflation persistence. We use yearly data for 14 countries and the Eurozone (ECB). We find that monetary policy transparency has a negative statistically significant impact on inflation persistence, while controlling also for important variables such as GDP growth, interest rates, economic openness and unit labour cost.

Internet use reduces the isolation or exclusion of individuals in specific socio-economic groups and, consequently, increases the quality of life, with this being especially the case for the elderly. Knowing that the elderly are becoming particularly active in dedicating time to the Internet, we provide evidence of the time that Spanish individuals aged 65 and older dedicate to two online activities: search and communications. We estimate a SUR model with data from the STUS for 2009-2010. Our main results indicate that being male has a positive influence on the time devoted to search on the Internet. Furthermore, time devoted to both Internet activities increases with higher levels of education and at the highest level of individual health.

After many years of teaching utility maximization in Microeconomics a certain paradoxical puzzle has come to our attention. It is very simple and straightforward, but we still find it hard to explain it to students. Our hope is that the distinguished community of theoretical economists may help us solve this mystery. After all, we would find it extremely unlikely that we are the first persons to identify this paradox.

This paper examines the perspectives of SMEs on Brexit and skill shortages using cross-sectional data of 2,969 SMEs from a UK Government’s Small Business survey for 2016. The logistic regression with clustered standard errors is applied to analyse the association between SMEs considering Brexit as a major business obstacle and the probability of SMEs identifying skill shortages in their businesses. The results show that firms with a shortage of managerial skills/expertise have a 6.5% higher probability to report that Brexit will affect their businesses, followed by difficulties in staff recruitment (4.5%) and shortage of skills within external labour markets (3.8%). Policy recommendations are provided.
