Growth and Unemployment: Towards a Theoretical Integration

We observe in the literature of the past decade some innovative contributions identified a relation between economic growth and long run unemployment. This set of contributions is composed of very few elements, all characterized by a high degree of heterogeneity about their features and about their final results.
In the first part of the survey we provide a classification of these early contributions. In the second part we explore some alternative formulations of the problem and we present a wider set of models displaying interesting features, able to promote further studies about the persistence of unemployment in a growing economy.     

The value added by government venture capital funds compared with independent venture capital funds

Government venture capital (GVC) funds have been a common policy initiative in European countries to overcome funding gaps in the promotion of early-stage ventures. In this work, we focus on the performance of such government funds. We compare the importance for the firm's development of post-investment, valueadded activities by GVC firms and independent venture capital (IVC) firms.We use a unique data set based on the results of a survey addressed to young high-techVC-backed firms from seven European countries. The survey gauged the importance of the contribution by the first lead investor in a variety of activity areas, as assessed by the investee companies. Attention was paid to potential adverse effects of the post-investment engagement of investors.Using a composite indicator of the value added, we find no statistically significant difference between the two types of investors. However, the profiles of value added differ across investor types, and, in particular, the contributions of IVC funds prove to be significantly higher than those of GVC funds in a number of areas, including the development of the business idea, professionalisation and exit orientation.     

Estimating and predicting multivariate volatility thresholds in global stock markets

We propose a general double tree structured AR‐GARCH model for the analysis of global equity index returns. The model extends previous approaches by incorporating (i) several multivariate thresholds in conditional means and volatilities of index returns and (ii) a richer specification for the impact of lagged foreign (US) index returns in each threshold. We evaluate the out‐of‐sample forecasting power of our model for eight major equity indices in comparison to some existing volatility models in the literature. We find strong evidence for more than one multivariate threshold (more than two regimes) in conditional means and variances of global equity index returns. Such multivariate thresholds are affected by foreign (US) lagged index returns and yield a higher out‐of‐sample predictive power for our tree structured model setting.

The cyclical behaviour of inventories: European cross-country evidence from the early 1990s recession

This paper employs data for a panel of firms from France, Italy and the UK to study the effect of the recession of the early 1990s on inventory investment, controlling for cyclical fluctuations at the firm level. The results clearly show some common patterns across countries, pointing to the relevance of financial factors (namely, the level of leverage) in propagating initial recessionary shocks. Moreover, Italian firms, especially if ‘small and young’, seem more likely to suffer from a reduction in the value of collateralizable assets possibly originated by restrictive policy actions.     

Business cycle comovement in the G-7: common shocks or common transmission mechanisms?

What are the sources of macroeconomic comovement among G-7 countries? Two main candidate explanations may be singled out: common shocks and common transmission mechanisms. In the article it is shown that they are complementary, rather than alternative, explanations. By means of a large-scale Factor Vector Autoregressive (FVAR) model, allowing for full economic and statistical identification of all global and idiosyncratic shocks, it is found that both common disturbances and common transmission mechanisms of global and country-specific shocks account for business cycle comovement in the G-7 countries. Moreover, spillover effects of foreign idiosyncratic disturbances seem to be a less important factor than the common transmission of global or domestic shocks in the determination of international macro-economic comovements.     

Patterns and determinants of international fragmentation of production: Evidence from outward processing trade between the EU and Central Eastern European countries

Patterns and Determinants of International Fragmentation of Production: Evidence from Outward Processing Trade between the EU and Central Eastern European Countries. — In this paper we investigate a specific form of international fragmentation of production, that is, the form giving rise to international trade for reasons of processing. Data on textile and apparel trade between EU countries and Central European countries show that the magnitude of trade for reasons of processing greatly overshadows that of final trade. The industry appears to be affected by a process of international fragmentation whose understanding requires a new definition of the concept of comparative advantage. Our analysis suggests that this fragmentation is activated by labor cost differentials as well as by reasons of geographic and cultural proximity.     

On Lipschitz continuity of the iterated function system in a stochastic optimal growth model

This paper provides qualitative properties of the iterated function system (IFS) generated by the optimal policy function for a class of stochastic one-sector optimal growth models. We obtain, explicitly in terms of the primitives of the model (i) a compact interval (not including the zero stock) in which the support of the invariant distribution of output must lie, and (ii) a Lipschitz property of the iterated function system on this interval. As applications, we are able to present parameter configurations under which (a) the support of the invariant distribution of the IFS is a generalized Cantor set, and (b) the invariant distribution is singular.     

Option Pricing For Jump Diffusions: Approximations and Their Interpretation

We derive a computable approximation for the value of a European call option when prices satisfy a jump-diffusion model with the coefficients depending explicitly on time. This is achieved by approximating the original coefficients with functions that are piecewise constant in time. We give an interpretation of the approximating option values, in particular in the context of a discrete-time model associated with the approximating continuous-time model.     

MVM's Nonlinear Internationalization: A Case Study

This article aims to contribute to the international and East-West business literature by discussing the nature of nonlinear internationalization based on a case study of an Italian firm, Meccanica Valle Metauro S.r.l., that had activities in Central and Eastern Europe and other countries and by identifying causes of nonlinearities. The study concludes that nonlinear internationalization may be caused by different internal and external factors and actors; that it can occur once or several times; that foreign market exit may be temporary (followed by re-entry) and permanent; and that de-internationalization does not always mean a failure for the firm.
