An explanation of the changes in the proportion of temporary workers in Spain

In this paper a theoretical model is developed to identify the main determinants of the proportion of temporary workers at firms. The outcomes show that the proportion of temporary workers has a counter-cyclical behaviour: it grows during the slump period up to 1995 and falls during the subsequent recovery. However, given the effect of the general economic cycle, firms that raise their sales or improve their market dynamism index tend to increase their proportion of temporary workers. This proportion also rises when the average labour cost decreases, firm size increases, and the knowledge capital stock diminishes.     

Return to tourist destination. Is it reputation,after all?

In this paper the hypothesis that repeated purchases in the tourism markets could be considered as a consequence of asymmetrical information problems is studied. This hypothesis is analysed with the case study of the island of Tenerife using the estimation of a count data model. It was found that the length of the stay and the information obtained from previous visits and/or relatives and friends might increase the return to a destination suggesting the presence of a reputation mechanism as proposed by Shapiro (1983 Shapiro, C. 1983. Premiums for high quality products as returns to reputations. Quaterly Journal of Economics, 98: 659–79. [Crossref], [Web of Science ®] , [Google Scholar]). The determinants of the willingness to return were also estimated, confirming the main results.     

Capital structure and institutional setting: a decompositional and international analysis

The legal and institutional setting is more and more influential in firms’ financial decisions. Our article analyses firms’ capital structure in an international framework in order to assess the different level of debt use across countries and to identify both common and differential explanatory factors. Although the level of financial leverage is quite different, the factors that have traditionally driven capital structure decisions have much in common in all the legal and institutional settings. The performance and size of the firm, the assets tangibility and the growth opportunities have a relevant but differential effect across the different institutional systems. Consequently, our results suggest that the legal and institutional system of each country does not only affect firms’ capital structure but also creates the conditions to explain a differential effect of the common determinants of firms’ financial choices.     

Real option value and random jumps: application of a simulation model

This article studies how sensitive real option valuations are to incorrect assumptions about the stochastic process followed by the state variables. We design a valuation model which combines Monte Carlo simulation and dynamic programming and provides an appropriate framework to evaluate the effect of estimation errors on both the value of real options and their critical frontier. Although the model is flexible enough to value American-type options contingent on a wide range of stochastic processes, we focus on the analysis of the effect of stochastic jumps. We apply our model to the valuation of an investment in the car parts industry documented in previous literature. Our results clearly show that underestimating this type of jumps might lead to substantial misjudgements in a firm's decision-making processes. For instance, it may lead to profitable projects being rejected when jump diffusion is low, or negative expanded net present value projects being accepted.     

Export activity,persistence and mark-ups

This article addresses the differences in margins across exporting and nonexporting firms. We jointly estimate a translog cost function, a variable factor share equation and price-cost margin equations to analyse the effect of persistence in export activity on margins. Results indicate that nonexporters have smaller margins than persistent exporters and firms that entered foreign markets during the nineties. However, larger export ratio is negatively associated with margins for persistent exporters. It suggests that efficiency advantages for exporters are partially compensated by higher competitive pressure in international markets. These results are in accordance with the predictions of Melitz and Ottaviano (2005 Melitz, MJ and Ottaviano, GIP. 2005. Market size trade, and productivity, NBER Working Paper Series No. 11393 (forthcoming in The Review of Economic Studies) [Google Scholar]).     

Asymmetric farm–retail price transmission and market power: a new test

A finite mixture model is used to estimate farm–retail price transmission in the US fresh strawberry market. Results suggest two distinct pricing regimes associated with off- and peak-harvesting seasons. The market power parameter is significant in the peak-harvest regime, but not in the off-peak regime. Moreover, price changes are transmitted completely throughout the marketing channel in the off-peak regime when the market power parameter is zero, but not in the peak-harvest regime when the market power parameter is positive. This suggests that produce buyers are more apt to exercise market power when farm supplies are abundant than when they are scarce, and that the exercise of such power causes the farm–retail price linkage to become asymmetric.     

Does grade retention affect students’ achievement? Some evidence from Spain

Grade retention practices are at the forefront of the educational debate. In this article, we measure the effect of grade retention on Spanish students’ achievement by using data from Programme for International Student Assessment (PISA). We find that grade retention has a negative impact on educational outcomes, but we confirm the importance of endogenous selection which makes observed differences between repeaters and nonrepeaters appear about 14% lower than they actually are. The effect on scores of repeating is much smaller (–10% of nonrepeaters’ average) than the counterfactual reduction that nonrepeaters would suffer had they been retained as repeaters (–24% of their average). Furthermore, those who repeated a grade during primary education suffered more than those who repeated a grade in secondary school, although the effect of repeating at both times is, as expected, larger.     

(How) Do research and administrative duties affect university professors’ teaching?

We analyse the interaction between university professors’ teaching quality and their research and administrative activities. Our sample is a high-quality individual panel data set from a medium-size public Spanish university that allows us to avoid several types of biases frequently encountered in the literature. Although researchers teach roughly 20% more than nonresearchers, their teaching quality is also 20% higher. Instructors with no research are 5 times more likely than the rest to be among the worst teachers. Over much of the relevant range, we find a nonlinear and positive relationship between research output and teaching quantity on teaching quality. Our conclusions may be useful for decision-makers in universities and governments.     

The Political Economy of Monetary Institutions in Brazil: The Limits of the Inflation-targeting Strategy, 1999–2005

Abstract

This paper suggests that the time-inconsistency approach is inadequate to analyze the political economy of monetary policy in Brazil. The paper develops an alternative theory that emphasizes distributive conflict, and argues that building credibility with a fixed exchange rate and through inflation-targeting was not central for stabilization. A contested-terrain analysis of the Brazilian case suggests that the current monetary regime benefits financial or rentier interests while the manufacturing sector and workers bear the costs of this policy.
