This article applies the Blinder–Oaxaca methodology in order to dissect the average earnings differentials between Greek workers and three different groups of immigrants into a part attributed to differences in characteristics and a part due to discrimination. It also seeks to identify the effect of assimilation (i.e. postmigration human capital) on immigrants’ earnings. We use information about 8429 individuals, of which 1185 are immigrants. The data are drawn from the Greek Labour Force Survey (2009). Our results suggest that discrimination is significantly higher for immigrants originating from non-EU countries than it is for EU foreigners, while it is negative for those who terminated education in Greece. Also, there is evidence that (i) post-migration human capital is a significant determinant of immigrants earnings, (ii) there is limited transferability of skills between sending countries and Greece and (iii) education is the main determinant of the wage gap between natives and immigrants. 相似文献

This paper investigates whether the sequence of current account deficits experienced in Greece over the 1950–1995 period
have been excessive. The degree of excessiveness is gauged by comparing the actual current account series to an optimal current
account measure derived from an intertemporal model of current account determination. The findings indicate that optimal consumption
smoothing did not take place over the sample period suggesting that the existing restrictions to the free flow of capital
were binding. More importantly the stock of net foreign liabilities was found to have been set on an unsustainable path following
the 1989/90 balance of payments crisis yet there is clear evidence that this tendency has been gradually reversed during the
last couple of years.

The Uruguay Round (1987–95) signaled the end of the Multifiber Agreement for textiles and clothing. The quota regime, in place since 1974, was decided, according to the Agreement on Textiles and Clothing, to be gradually eliminated by the year 2005. As a result, prices of cotton-yarn in the world markets decreased, affecting producers in all cotton-yarn exporting countries, including Greece. At the same time, the labor cost in western industrialized countries remained high, or even increased, exerting further pressure on yarn producers. The present paper examines these changes for the cotton-yarn industry in Greece. We use a multi-market partial-equilibrium model which allows us to take into account simultaneous input and output price changes, relevant for the industry under study. Findings show that, after the implementation of the program for the gradual elimination of quotas, producers' welfare decreased whereas consumers noted substantial increases in welfare transfers. 相似文献

The nonlinear dynamic relationship of exchange rates: Parametric and nonparametric causality testing 总被引:1,自引:0,他引:1
The present study investigates the linear and nonlinear causal linkages among six currencies denoted relative to United States dollar (USD), namely Euro (EUR), Great Britain Pound (GBP), Japanese Yen (JPY), Swiss Frank (CHF), Australian Dollar (AUD) and Canadian Dollar (CAD). The data spans two periods between 3/20/1991 and 3/20/2007. We apply a new nonparametric test for Granger non-causality by Diks and Panchenko [Diks, C., Panchenko, V., 2005. A note on the Hiemstra–Jones test for Granger noncausality. Studies in Nonlinear Dynamics and Econometrics 9 (art. 4); Diks, C., Panchenko, V., 2006. A new statistic and practical guidelines for nonparametric Granger causality testing. Journal of Economic Dynamics & Control 30, 1647–1669] and the linear Granger test on the return time series. To detect strictly nonlinear causality, we examine the pairwise VAR-filtered residuals as well as in a six-variate formulation. We find remaining significant bi- and uni-directional causal nonlinear relationships in the series. Finally, we investigate causality after controlling for conditional heteroskedasticity using a GARCH–BEKK model. Whilst the nonparametric test statistics are smaller in some cases, significant nonlinear causal linkages persisted even after GARCH filtering during both periods. This indicates that currency returns may exhibit asymmetries and statistically significant higher-order moments. 相似文献

In this paper, we analyse the dynamic relationship between hours worked per employee (per self-employed) and marginal income tax-rate shocks in terms of both a comparative-dynamics model and a stochastic general equilibrium econometric model. The econometric model is estimated for Germany, UK and USA over the post-1960 period using the GMM estimation technique. Estimates in both models show that increases in the marginal income-tax rate exert negative effects on hours worked by both employees and the self-employed, but the response of the employees who are subject to tax withholding is stronger than the response of the self-employed. 相似文献

We are at a turning point in the debate on the ethics of Artificial Intelligence (AI) because we are witnessing the rise of general-purpose AI text agents such as GPT-3 that can generate large-scale highly refined content that appears to have been written by a human. Yet, a discussion on the ethical issues related to the blurring of the roles between humans and machines in the production of content in the business arena is lacking. In this conceptual paper, drawing on agenda setting theory and stakeholder theory, we challenge the current debate on the ethics of AI and aim to stimulate studies that develop research around three new challenges of AI text agents: automated mass manipulation and disinformation (i.e., fake agenda problem), massive low-quality content production (i.e., lowest denominator problem) and the creation of a growing buffer in the communication between stakeholders (i.e., the mediation problem). 相似文献
