How do entrepreneurial firms establish cross-border relationships? A global value chain perspective

In the past decade, international entrepreneurship has centered largely on the internationalization of small- to medium-sized enterprises through dispersed production networks. Although network relationships are crucial in entrepreneurial internationalization, the dynamics underlying the establishment and coordination of interfirm linkages remain uncertain and unclear. Using a global value chain framework, this article uses a case study to explore how two small enterprises engage in the establishment of a cross-border alliance. Findings suggest that the global value chain approach provides a better understanding of the governance of global relationships. The study also denotes the room for further improvement in this area.     

Services Provision and Temporary Mobility: Freedoms and Regulation in the EU

International posting of workers and mobility of self‐employed service suppliers lie between outright migration and trade in goods: their regulation, for both distributional and market‐correcting purposes, is not as difficult to harmonise as that of labour markets, but personal mobility is more visible and socially intrusive than product market interactions. This paper analyses economic and legal tensions between national regulatory frameworks and international competition in these areas, in both the intra‐EU and global contexts, highlighting how interactions between the external and internal roles of the European Commission may foster efficient integration of markets and policies in this and other fields.

Climate Change and Adaptation: The Case of Nigerian Agriculture

The present research offers an economic assessment of climate change impacts on the four major crop families characterizing Nigerian agriculture. The evaluation is performed by shocking land productivity in a computable general equilibrium model tailored to replicate Nigerian economic development up to 2050. The detail of land uses in the model has been increased by differentiating land types per agro-ecological zones. Uncertainty about future climate is captured, using, as inputs, yield changes computed by a crop model under ten general circulation models runs. Climate change turns out to be negative for Nigeria in the medium term, with production losses and increase in crop prices, higher food dependency on foreign imports, and GDP losses in all the simulations after 2025. In a second part of the paper, a cost effectiveness analysis of adaptation in Nigerian agriculture is conducted. The adaptation practices considered are a mix of cheaper “soft measures” and more costly “hard” irrigation expansion. The main result is that the cost effectiveness of the whole package depends crucially on the possibility of implementing adaptation by exploiting low-cost opportunities which show a benefit-cost ratio larger than one in all the climate regimes.     

Affiliated mutual funds and analyst optimism

This paper extends the literature on analyst optimism. Our analysis of a large sample of recommendations issued from 1995 through 2006 indicates that sell-side analysts are likely to assign frequent and favorable ratings to a stock after the analysts’ affiliated mutual funds invest in that stock. Controlling for a number of variables, including the ties between analysts and investment banks, we find that the greater the portfolio weight of a stock in the fund family, the more optimistic the stock ratings from affiliated analysts become. Since 2002, analysts’ optimism on stocks held by affiliated mutual funds has declined. However, an analyst's decision of upgrading a stock to a “strong buy” rating is still significantly associated with the portfolio weight of that stock in the fund family.     

Effectiveness of monetary policy and limited asset market participation: Neoclassical versus Keynesian effects

This paper investigates the effects of limited asset market participation on the effectiveness of monetary policy in a New Keynesian Dynamic Stochastic General Equilibrium model. Although an increase in consumers who cannot access financial markets reduces the effects of interest rate policies through consumption inter-temporal allocation (neoclassical or permanent income effect), we find an opposite result: monetary policy becomes more effective as the degree of financial market participation falls. The reason has a very Keynesian flavor.     

The co-evolution of tax evasion,social capital and policy responses: a theoretical approach

The dynamic model presented in this paper intends to account for the evidence, which appears to be particularly significant for Italy, of the incidence of tax evasion in a certain region being negatively correlated with the level of social capital existing in that region. Besides including social capital among the determinants of tax evasion, we extend the model so as to incorporate a mechanism whereby the existing volume of opportunistic behavior—which is proxied by the level of tax evasion—has negative effects on the formation of new social capital, thus helping to explain how regional differences in the endowment of social capital and in the incidence of tax evasion co-evolve and why they tend to be highly persistent. The model seeks also to capture the fact that in a democracy the political determination necessary to effectively repress tax evasion depends on the voters’ propensity toward the phenomenon. Hence, one should expect that–in areas where a relatively large (small) number of citizens are tax cheaters—the consensus in favor of tough policies against tax evasion tends to be weak (strong) and short (long) lasting. Consistently with this intuition, the model shows that regions where social capital is relatively low and tax evasion is relatively high can do better in the long run (i.e., they can reach a steady state characterized by a higher level of social capital and a lower level of tax evasion) when tax-enforcement policies are determined at the national level rather than at the regional level. The opposite holds for regions where social capital is relatively high and tax evasion is relatively low.     

Calvo vs. Rotemberg in a trend inflation world: An empirical investigation

This paper estimates and compares New-Keynesian DSGE monetary models of the business cycle derived under two different pricing schemes—Calvo (1983) and Rotemberg (1982)—under a positive trend inflation rate. Our empirical findings (i) support trend inflation as an empirically relevant feature of the U.S. great moderation; (ii) provide evidence in favor of the statistical superiority of the Calvo setting; (iii) point to a substantially lower degree of price indexation under Calvo. We show that the superiority of the Calvo model is due to the restrictions imposed by such a pricing scheme on the aggregate demand equation.
