The regional wage gap in the Spanish hospitality sector based on a gender perspective

In this work we estimate human capital returns in the Spanish hospitality sector using an expanded version of the Mincer wage equation (1974). In addition, wage differences in the main tourist regions are quantified using the wage decomposition of Oaxaca (1973) and Blinder (1973) from a gender perspective. Using data from the 2006 Spanish Wage Structure Survey (Encuesta de Estructura Salarial), all the regions under analysis show lower education returns in the hospitality sector when compared to other private services. The same results are found for the other human capital variables used. There are significant differences in education returns between regions, especially in Catalonia and the Canary Islands. The main wage gap in the Canary Islands and the Madrid region is due to differences in returns in the observed variables, whereas in other regions most of the differences are due to the resources allocated. Furthermore, gender wage differences are found in all the regions. The largest estimated wage gap between men and women occurs in the Balearic Islands followed by Catalonia and the Community of Valencia. In contrast, equality between genders is greater in the Community of Madrid.     

Does employment protection help immigrants? Evidence from European labor markets

High levels of employment protection reduce hiring and firing and have a theoretically ambiguous effect on the employment level. Immigrants, being new to the labor market, may be less aware of employment protection regulations and less likely to claim their rights, which may create a gap between the costs for employers of hiring a native relative to hiring an immigrant. This paper tests that hypothesis drawing on evidence for the EU and on two natural experiments for Spain and Italy. The results suggest that strict employment protection legislation (EPL) gives immigrants a comparative advantage relative to natives. Stricter EPL is found to reduce employment and reduce hiring and firing rates for natives. By contrast, stricter EPL has a much smaller effect on immigrants.     

Does the Welfare State Destroy the Family? Evidence from OECD Member Countries

We study the effect of the size of the welfare state on demographic trends in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e., the number of relevant parties involved in the legislative process), we show that an expansion in the welfare state increases fertility, marriage, and divorce rates with a quantitatively stronger effect on the marriage rate. We conclude that the welfare state supports family formation in the aggregate. Further, we find that the welfare state decouples marriage and fertility, and therefore alters the organization of the average family.     

Milk sales and dietary diversity among the Maasai

In Maasai culture, responsibilities are traditionally divided between genders. Men are in charge of grazing and managing the livestock herds. Women take care of the family, administer food supplies, and are responsible for milking. For them, balancing home consumption of milk (for the family and for the calves), milk sale, and food purchase is a major task. In this article, we first investigate how different milk sales groups vary regarding the use of different food items and the respective quantities consumed by the enkaji, i.e., a Maasai subhousehold. Then, we address the commercialization decision and assess the effect of milk sales on the enkaji's food item use and food consumption. Using the data of Maasai enkajijik in the milk catchment area of a milk collection center in Ngerengere, Tanzania, we estimate the effects by employing propensity score matching procedures. Our findings suggest that milk sellers, especially those selling to the milk collection center, have a more diverse diet. In terms of per person consumption, the groups are markedly similar. Therefore, we conclude that income generated by milk sales is invested in diet diversification rather than in increasing the quantity of food consumed, hence the enkajijik appear not to make use of caloric terms of trade.     

W. H. Hutt (1899–1988): Free Markets and Social Justice

W.H. Hutt reaffirmed the principles of classical economics and classical liberalism and, by applying them to urgent issues he observed in the world around him, he demonstrated the contemporary relevance of freedom and competitive institutions. A wide‐ranging critique of Keynes was founded upon a classical analysis of the labour market, while his trenchant opposition to apartheid advanced along economic and political paths. Hutt questioned the justice of the accumulation of wealth from the exploitation of monopoly power over generations. In all of these respects there are affinities between Hutt's thought and that of ‘Bleeding Heart Libertarians’.     

Cooperation In R&D With Spillovers And Delegation Of Sales ∗

Cooperation in several phases of the innovation process is viewed by antitrust authorities with suspicion. They face the dilemma between providing the right incentives for the appro-priability of returns to R&D and the risks of diminishing product market competition. The current legislation in the European Union and the United States gives special treatment to cooperation in R&D and the joint exploitation of results (extended cooperation).

We study several collusive regimes for a class of examples in which vertical relations are explicitly introduced. Regarding antitrust policy implications we fmd that: a) there is an ana-lytical justification to a ‘rule of reason’ treatment for extended cooperation in research joint ventures and, b) individual exemptions, though restrictive of competition, might be welfare improving.     

The Layoff Rat Race*

We investigate how discretionary investments in general and specific human capital are affected by the possibility of layoffs. After investments are made, firms may have to lay off workers, and will do so in inverse order of the profit that each worker generates. Greater skill investments, especially in specific human capital, contribute more to a firm's bottom line, so that workers who make those investments will be laid off last. We show that as long as workers' bargaining positions are not too weak, workers invest in specific human capital in order to reduce layoff probabilities. Indeed, workers over‐invest in skill acquisition from a social perspective whenever their bargaining power is strong enough, even though they only receive a share of any investment. More generally, we characterize how equilibrium skill investments are affected by the distribution of worker abilities within firms, the probability that a firm will downsize, and the distribution of employment opportunities in the economy.

Determinants of the Choice of Migration Destination*

This paper examines migrants’ choice of destination conditional on migration. The study uses data from two rounds of Nepal Living Standard Surveys and a Population Census and examine how the choice of a migration destination is influenced by various covariates, including income differentials across possible destinations. We find that migrants move primarily to nearby, high population density areas where many people share their language and ethnic background. Better access to amenities is significant as well. Differentials in average income across destination districts are significant in univariate comparisons but not once we control for other covariates. Differentials in consumption expenditures are statistically significant but smaller in magnitude than other determinants. It is differentials in absolute, not relative, consumption between destination districts that are correlated with the destination of work migrants. Except for the latter, results are robust to different specifications and datasets.     

Does accounting conservatism pay?

We investigate whether or not there is a link between conservative accounting practices and the sensitivity of executive pay to accounting performance. Using several accrual‐based measures of accounting conservatism as well as alternative measures of accounting performance, we estimate an econometric model of CEO compensation that incorporates the interaction of accounting conservatism and accounting performance. Consistent with optimal contracting theory, we find that the sensitivity of executive pay to accounting performance is higher for firms that report conservative accounting earnings. These results support the hypothesis that accounting conservatism, by limiting earnings management opportunities and improving the reliability of accounting performance measures, allows firms to formulate contracts that tie executive compensation more closely to accounting performance.
