Export Premia and Sub-Contracting Discount. Passive Strategies and performance in Domestic and Foreign Markets

This paper contributes to the literature on firms’ productivity and exporting decisions by analysing the role played by organizational choice aspects. Rather than setting up a vertically integrated structure, manufacturers may act as subcontractors in both domestic and foreign markets, and produce to satisfy the requirements of other firms. A very simple model is presented where the most productive firms self-select into exporting, while the least productive ones work as sub-contractors serving the domestic market only. These predictions are tested using a sample of Italian firms observed in the 1998-2003 period. The results of our estimates highlight a ranking of firms consistent with a priori expectations, and provide a clear indication that passive exporters (i.e. using sub-contracting in foreign markets)display lower TFP values as compared to direct exporters. Moreover, only the latter category exhibits higher pre-entry productivity levels and growth rates as well as higher post-entry TFP growth rates. Such findings are consistent with both the self-selection hypothesis and the learning by exporting explanation.Export Premia, Sub-contracting Discount, Total Factor Productivity, Firm Heterogeneity

Spreading of an infectious disease between different locations

The endogenous adaptation of agents, that may adjust their local contact network in response to the risk of being infected, can have the perverse effect of increasing the overall systemic infectiveness of a disease. We study a dynamical model over two geographically distinct but interacting locations, to better understand theoretically the mechanism at play. Moreover, we provide empirical motivation from the Italian National Bovine Database, for the period 2006-2013.Comment: 22 pages (and 10 pages for appendix); 11 figures (2 in appendix

Job Separations and Informality in the Russian Labor Market

In the years 2003-2008 the Russian economy experienced a period of strong and sustained growth, which was accompanied by large worker turnover and rising informality. We investigate whether the burden of informality falls disproportionately on job separators (displaced workers and quitters) in the Russian labor market in the form of informal employment and undeclared wages in formal jobs. We also pursue the issues whether displaced workers experience more involuntary informal employment than workers who quit and whether informal employment persists. We find a strong positive link between separations and informal employment as well as shares of undeclared wages in formal jobs. Our results also show that displacement entraps some of the workers in involuntary informal employment. Those who quit, in turn, experience voluntary informality for the most part, but there seems a minority of quitting workers who end up in involuntary informal jobs. This scenario does not fall on all separators but predominantly on those with low human capital. Finally, informal employment is indeed persistent since separating from an informal job considerably raises the probability to be informal in the subsequent job.job separations, informality, Russia

Job Separations, Job loss and Informality in the Russian Labor Market

Having unique data we investigate the link between job separations (displacement and quits) and informal employment, which we define in several ways posing the general question whether the burden of informality falls disproportionately on job separators in the Russian labor market. After we have established positive causal effects of displacement and quits on informal employment we analyze whether displaced workers experience more involuntary informal employment than their non-displaced counterparts. Our main results confirm our contention that displacement entraps some of the workers in involuntary informal employment. Those who quit, in turn, experience voluntary informality for the most part, but there seems a minority of quitting workers who end up in involuntary informal jobs. This scenario does not fall on all the workers who separate but predominantly on workers with low human capital. We also pursue the issue of informality persistence and find that informal employment is indeed persistent as some workers churn from one informal job to the next. Our study contributes to the debate in the informality literature regarding segmented versus integrated labor markets. It also contributes to the literature on displacement by establishing informal employment as an important cost of displacement. We also look at the share of undeclared wages in formal jobs and find that these shares are larger for separators than for incumbents, with displaced workers bearing the brunt of this manifestation of informality

Does ICT Investment Spur or Hamper Offshoring? Empirical Evidence from Microdata

In this paper we provide empirical evidence on the effect of ICT investment on the propensity to offshore for a large sample of Italian manufacturing firms. Contrary to previous literature focusing on the service sector, after taking into account the endogeneity of ICT investment in the offshoring decision equation we find a negative and significant effect of ICT on the propensity to offshore some stages of the production process. Furthermore this effect turns out not to depend on the type of ICT investment and applies both to hardware and software/telecommunication expenditures. A potential explanation for our finding is that ICT investments in manufacturing increase the complementarity of production processes within the firm, thereby reducing the incentive to offshore. Our results seem therefore to suggest that negative exogenous shocks to ICT prices–possibly induced by targeted policy programs aimed at the diffusion of ICT technologies–do not favor offshoring of manufacturing activities.ICT Investment, Offshoring, Maximum Likelihood System Estimation

An Experimental Evaluation of the Serial Cost Sharing Rule

This paper proposes an experimental test of the strategic equilibrium properties of the serial cost sharing rule originally proposed by Shenker (1990) and then analyzed by Moulin and Shenker (1992). We report measure of the performance and efficiency of the serial mechanism by comparing the choices and payoffs attained by the subjects to the expected first best allocations. Experimental evidence shows that, while some learning is needed, the serial mechanism leads to almost efficient allocations.
