The Impact

In this paper, the scope is to study whether and how the COVID-19 situation affected the unemployment rate in Greece. To achieve this, a vector autoregression (VAR) model is employed and data analysis is carried out. Another interesting question is whether the situation affected more heavily female and the youth unemployment (under 25 years old) compared to the overall unemployment. To predict the future impact of COVID-19 on these variables, we used the Impulse Response function. Furthermore, there is taking place a comparison of the impact of the pandemic with the other European countries for overall, female, and youth unemployment rates. Finally, the forecasting ability of such a model is compared with ARIMA and ANN univariate models.

ABSTRACT Purpose: We analyzed the impact of board directors with foreign experience on the accounting and market performance of companies listed on the Brazilian Stock Exchange (B3). Originality/value: We show unpublished empirical evidence about the relationship between the foreign experience of board directors and the performance of Brazilian firms. Knowing this relationship better contributes to the formulation of internal policies for the qualification of senior management, in addition to being valuable to shareholders, especially in a context of weak legal protection, as it is in Brazil. Design/methodology/approach: We collected data from 230 companies between 2010 and 2016, submitted it to unbalanced panel data regressions using the Systemic Generalized Method of Moments (GMM-Sys). Findings: The results suggest that the higher the proportion of board members with academic and professional foreign experience, the lower their accounting and market performance. This finding can be justified by institutional isomorphism, in which having an experience abroad would be a myth, a status institutionalized by the Brazilian society. In addition, foreign owners and directors face cultural barriers and would have less knowledge of the local environment, which would increase information asymmetries, impacting negatively in firms’ performance. On the other hand, an increase in the number of foreigners on the board positively influences the market value of companies, since, by having weaker local power networks and, consequently, less possibility to obtain private benefits, the investors could value companies with this characteristic.

Over Time

The agricultural sector is being supported in Turkey, as well as in the world. The issue of competitiveness is observed in agriculture, despite supports. This study aims at investigating the impact of agricultural supports in Turkey on competitiveness of agricultural products. Vector autoregression (VAR) model has been adopted in the study. The internal terms of trade (TOT), percentage producer support estimate (PSE), and the producer nominal protection coefficient (NPC) variables have been included in the model. The internal terms of trade in Turkey have developed over time against the benefit of agricultural sector. PSE has had a significant impact on TOT. Therefore, the use of PSE as a political variable has been concluded as a significant. Means of support must be discussed in Turkey more than the amount of supports. In particular, supports that will provide farmers with competitive advantage and boost up product farmyard prices will be more efficient and beneficial for farmers.
