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. I would like to thank D. Cass, H. Polemarchakis and P. Siconolfi for their helpful comments.     

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.

Money secrets: How does trade secret legal protection affect firm market value? Evidence from the uniform trade secret act

Research summary : We investigate the impact of trade secret legal protection on firm market value in the context of acquisitions. On one hand, market value may increase because trade secret assets become better protected from rivals. On the other hand, market value may decrease because trade secret protection reduces information about the target and its competitors available to potential buyers, increasing uncertainty about its value. Buyers will discount their offers in expectation of being compensated for riskier deals. Using a sample of private equity investments in the United States, we find that trade secret protection has a positive effect in industries with high mobility of knowledge workers, but a negative effect in industries with (1) high resource–value uncertainty and (2) high poor‐investment risk. Managerial summary : We argue that an increase in trade secret legal protection might not unequivocally benefit firm owners when selling their business. A stronger trade secret protection increases the market value of firms in industries with high workers' mobility, but it decreases the market value of firms in industries with uncertain resource value and/or high risk of poor‐acquisition investments. Based on the contingent effect of trade secret protection, companies may want to adjust their strategic decisions, including where to locate or relocate, based in part on whether they will derive benefits or suffer losses when trade secrets are better protected. Finally, our study should help policymakers understand more fully the economic impact of government policies associated with trade secrets. Copyright © 2016 John Wiley & Sons, Ltd.     

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.     

Rethinking the import-productivity nexus for Italian manufacturing

We provide evidence on the firm level productivity effects of imports of intermediates. By exploiting a large panel of Italian manufacturing firms, we are able to separately explore the role of importing from high and low income countries. Importing does not permanently affect the firm productivity growth. This finding holds both when we test for the import entry by means of Propensity Score Matching techniques and when we analyse the import intensity within a dynamic panel data model framework. On the contrary, we confirm the existence of self-selection into importing. Also, our evidence supports the learning-by-exporting effects in Italian manufacturing and we prove that this result is robust to the control of firm import activity.     

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.

Mercantilism: a materialist approach

ABSTRACT

Historians and economists have shown renewed interest in mercantilism over the last couple of years. From this interest, a dispute has arisen about whether mercantilism should be seen as an incoherent economic thought or if it is possible to ‘reconstruct’ its basic principles. In line with this latter attempt, this paper is intended to provide a materialist explanation for varying degrees of belief in shared mercantilist assumptions. My hypothesis is that belief in mercantilist assumptions is significantly dependent upon how economic and security issues materially interact in a given time and space, with uncertainty and insecurity profoundly favouring mercantilist dispositions in economic thought. To analyse this hypothesis, the paper sets the first steps for relating the credibility of mercantilism with changes in British economic and military history from the sixteenth to the nineteenth century. Section 3 presents ideas to further investigate this hypothesis. Section 4 concludes the paper.
