The structure of the set of sunspot equilibria in economies with incomplete financial markets

Summary This paper considers the set of equilibria of two-period, sunspot economies withS purely extrinsic states of nature in the second period andI assets with linearly independent nominal payoffs. The span of the payoff matrix contains the vector [1, ... , 1] (i.e., inside money). The set of economies is described in terms of (sunspot-invariant) utility functions. IfS>I> 0, there is an open, dense set of economies such that, given a vector of no arbitrage asset prices, the set of equilibrium allocations contains a smooth manifold of dimensionS—I. Such a manifold contains at least one nonsunspot equilibrium (and at most a finite number of such equilibria).The paper was written while I was a visitor at C.O.R.E., Universitè Catholique de Louvain, with the financial support of a S.P.E.S. fellowship.

The effects of employment protection: Learning from variable enforcement

Employment protection legislation (EPL) is not enforced uniformly across the board. There are a number of exemptions to the coverage of these provisions: firms below a given threshold scale and workers with temporary contracts are not subject to the most restrictive provisions. This within-country variation in enforcement allows us to make inferences on the impact of EPL which go beyond the usual cross-country approach. In this paper we develop a simple model which explains why these exemptions are in place to start with. Then we empirically assess the effects of EPL on dismissal probabilities and on the equilibrium size distribution of firms. Our results are in line with the predictions of the theoretical model. Workers under permanent contracts in firms with less restrictive EPL are more likely to be dismissed. However, there is no effect of the exemption threshold on the growth of firms.     

IMMIGRANT RELATIVE WAGES AT THE GREAT RECESSION: EVIDENCE WITH MATCHED EMPLOYER‐EMPLOYEE DATA FOR SPAIN

The article examines relative wages of immigrants in Spain, with a particular focus on the impact of the Great Recession. The empirical analysis is restricted to men and is based on matched employer‐employee microdata and the decomposition techniques of Juhn et al. (1991, 1993) and Fortin et al. (2011). Our results show that the significant native‐immigrant wage gap that exists both in terms of average wages and of differentials along the wage distribution is essentially explained by differences in the endowments of observed characteristics so that, in general, immigrants tend to receive a similar wage treatment than Spaniards with analogous observed attributes. On the other hand, the Great Recession has had a noticeable impact on the relative wages of immigrants, given that the significant increase of the native‐immigrant wage gap observed during the previous expansionary period was mitigated during the economic downturn due to composition effects arising from the severe employment destruction pattern.     

The Dynamics of Earnings Forecast Management

This paper examines whether firms manage analyst forecasts andthe associated value consequences. We find that earnings forecaststend to grow pessimistic over the forecast horizon and theseforecast changes and their timing are key determinants of whetherfirms generate positive earnings surprises: Late forecasts thatraise (lower) the consensus sharply reduce (raise) the probabilityof positive surprises. This findng is the opposite of that predictedif consensus revisions reflected new information arrival. Investorsseem to be "misled": downward consensus revisions lead to largeabnormal returns following the earnings announcement. Paradoxically,downward forecast management reduces post-announcement shareprice, as the impact of reduced forecasts dominates the gainfrom generating positive surprises.     

Setting the minimum wage

The process leading to the setting of the minimum wage so far has been overlooked by economists. There are two common ways of setting national minimum wages: they are either government legislated or the byproduct of collective bargaining agreements, which are extended erga omnes to all workers. We develop a simple model relating the level of the minimum wage to the setting regime. Next, we exploit a new data set on minimum wages in 68 countries having a statutory national minimum level of pay in the period 1981–2005. We find that a Government legislated minimum wage is lower than a wage floor set within collective agreements. This effect survives to several robustness checks and can be interpreted as a causal effect of the setting regime on the level of the minimum wage.     

Internal And External Adjustment To New Technologies

Schumpeterian creative destruction occurs not only at the industry level, but also with each firm trying to maintain or improve its position in the technology race. Based on a rich data set on more than 4,000 German business units, this paper shows that the simultaneous occurrence of hiring and separations is more likely in firms with the most advanced technologies in use than in units more distant from the technological frontier. This positive relation between technological advance and creative destruction documented also by churning and ‘excess job reallocation equations - holds particularly in recovery years, while it is weak during a recession. The explanation provided for this finding in the paper is that firms can also improve technologies by upgrading machinery and/or retraining workers, and these ‘implementation’ costs arc likely to be lower during economic downturns.     

SMEs and CSR: An Approach to CSR in their Own Words

The academic literature reveals the need to undertake more in-depth field studies in order to discover the organisational culture, the difficulties and the perceptions surrounding CSR in SMEs. This study presents the results of analysis of four case studies on Catalan companies that stand out for their social and environmental practices. The conclusions of this paper are the result of dialogue with the main actors – four medium-sized companies – focusing on their actions, understandings and resistance with regard to CSR. The methodological perspective used was Grounded Theory, with the aim of the study being to contribute towards formalising CSR in SMEs, in their daily practices, by analysing some primary data. The results obtained show how difficult it is for SMEs to understand CSR, beyond the explanation of the specific practices carried out by the companies. They highlight the role played by the values of the founding director in the implementation of CSR programmes; they reveal that SMEs still have a long way to go towards learning how to inform both internal and external stakeholders of their best practices, and; finally, they show the interesting links that SMEs establish between responsible practices, improved competitiveness and economic results. Finally, the text points out the implications that the results of this analysis may have on creating ways of promoting CSR in SMEs. We believe that, in light of the opinions expressed by the companies, public organisations should try to concentrate on creating a favourable framework for responsible competitiveness, as a way to deal with CSR when addressing SMEs.David Murillo is a Researcher at the Institute for the Individual, Corporations and Society (IPES), ESADE Business School, Universitat Ramon Llull and Academic Assistant at the same institution.

Beyond Eurosclerosis

Europe no longer suffers from Eurosclerosis; unemployment, notably long-term unemployment, had decreased substantially for more than a decade. Mobility across labour market states increased in those countries where unemployment has been falling the most. Institutional reforms -- such as declining employment protection for new entrants in the labour market and less generous unemployment benefits -- account for this increase in mobility. Focusing on these reforms, we rationalize why EU workers, including those with permanent contracts, are increasingly unhappy about labour market conditions in spite of the disappearance of mass unemployment in Europe. Due to these perceptions, policy reversals cannot be ruled out. Governments wishing to minimize the risk of going back to Eurosclerosis should move towards flexicurity configurations, compensating workers for higher risks of job loss, and introduce tenure tracks to the labour market, preventing the development of dual labour market structures. This would avoid dissipating the employment gains of the last decade during this recession.

Efficiency, subsidies, and environmental adaptation of animal farming under CAP

The purpose of this article is to model the interaction between the targets of the current Comman Agriculture Politic (CAP): environmental adaptation, subsidies, and efficiency of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal‐oriented farm in the sample. The production frontier and efficiency index for each type of farm (assuming no specific production functions) are identified using Data Envelope Analysis (DEA) techniques. We then address the relationship between relative efficiency, farm size, and environmentally friendly behavior by carrying out a nonparametric regression of efficiency, on economic size, a proxy for the degree of environmental appropriateness, and regional dummies. Calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered. Finally, we look for relations between subsidies and factors such as farm size, efficiency, and environmentally friendly behavior. One key result shows that, on average direct payments generally tend to increase efficiency. However, in most of the cases the mean efficiency decreases as the percentage of direct payments rises. Direct payments are found to be positively related to environmentally friendly production, at least in Germany. However, in general, the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient.
