On the interaction between public and private capital in economic growth

This paper introduces two forms of interaction between private and public capital in an endogenous growth model in which productive government expenditure takes the form of a stock-variable and public capital is used in part as an input in the production of final output and in part to increase its own supply. While the first form of interaction involves the stocks of the two capital-goods and takes place within the final output sector through the specification of the aggregate production function (Cobb?CDouglas vs. CES), the second one concerns the rates of investment in the two kinds of capital. The share of productive public expenditure devoted to output production can be either exogenous or endogenous. Our results suggest that when this share is exogenous, along the balanced growth path the optimal growth rate of the economy is a positive function of the degree of complementarity between the two forms of investment. When the share of productive public expenditure devoted to output production is endogenous, the public capital share in GDP becomes, along with the model??s preference parameters, an important determinant of the economy??s long run growth. We also find that the optimal growth rate is an increasing function of the elasticity of substitution between public and private capital inputs in goods production, and is independent of the complementarity/substitutability between the two forms of investment.     

Turbulence underneath the big calm? The micro-evidence behind Italian productivity dynamics

Italy ranked last in terms of manufacturing productivity growth according to OECD estimates over the last decade, with a flat, if not declining, trend. In this work we investigate the underlying firm-level dynamics of enterprises on the basis of a database developed by the Italian Statistical Office (ISTAT) covering the period 1989?C2004 and containing information on more than 100,000 firms. Over this period not only have the indicators of the central tendency of the distribution of labor productivity not significantly changed, but also the whole sectoral distributions have remained relatively stable over time, with their support at least not shrinking, or even possibly widening, over time. This is even more surprising if one takes into consideration the ??Euro?? shock that occurred during the period investigated. On the contrary, we observe that inter-decile differences in productivity have been increasing. Further, heterogeneous firms?? characteristics (i.e. export activity and innovation) seem to have contributed to boosting such intra-industry differences. Given such wide heterogeneities we resort to quantile regressions to identify the impact of a set of regressors at different levels of the conditional distribution of labor productivity. One phenomenon that we observe is what we call a tendency toward ??neo-dualism?? involving the co-existence of a small group of dynamic firms with a bigger ensemble of much less technologically progressive ones.     

A Polarization Index for Overlapping Groups

The well‐known index of income bipolarization proposed by Wolfson (1994) requires two groups to be split according to the median income and, therefore, to be non‐overlapping. The aim of this paper is to propose a new polarization index in the spirit of the Wolfson index. It allows for any possible partition of the population in two or more (also overlapping) groups. The new index maintains the simplicity and immediate comprehension of the Wolfson index, though being much more flexible. An application is then provided for German and Italian income data.

Risk of poverty in Southern Europe

We analyze whether the risk of poverty deteriorates with the crisis in France, Greece, Italy and Spain, for different categories of households, individual features and policy instruments, such as the regional European Structural Funds. We find that the impact of the economic recession was heterogeneous, deteriorating the status of temporary workers, self-employed, single and female-headed households, while the risk of poverty decreased relatively for larger households with dependent children and elderly members. We also find that targeted funds toward human capital investment are associated to decreasing the risk of poverty, but the crisis slowed down their effects.     

The Impact of the Global Financial Crisis and the Role of External and Internal Factors in Emerging Economies

This article assesses the impact of trade, capital openness and institutions on emerging economies’ output loss during the “Great Recession.” The fixed-effect estimates of an unbalanced panel of 122 emerging countries observed from 2008 to 2010 yield three main results. First, trade openness has exacerbated output loss. Second, capital openness can help mitigate the negative impact of an external shock, but this is conditional on the level of financial development. Finally, the results also point out that the interrelations between financial and institutional development affect the crisis’s severity.     

Export price adjustments under financial constraints

Exploiting data on the product‐destination‐level transactions of a large panel of Italian firms, we provide evidence that financial constraints affect price variation across exporters. Constrained exporters charge higher prices than do unconstrained firms that export to the same product‐destination market. This pattern is the result of a two‐fold effect. Distressed firms pass on their higher production costs through prices. However, they also charge higher mark‐ups. We explain this evidence referring to models in which rival firms produce different brands of the same product for customers with significant switching costs and producers face capital market imperfections when they need external financing. Our empirical investigations corroborate this explanation: price gaps are higher when switching costs or other forms of demand rigidity are expected to be more relevant.     

Indirect exporters and importers

This paper analyses the relation between firms’ productivity and the different modes of participation in international trade. In particular, it accounts for the possibility that firms can not only export their products, but also internationally source their inputs, either directly or indirectly. Using a cross section of firm level data for several advanced and developing economies, the study confirms the productivity-sorting prediction according to which domestic firms are less efficient than those that resort to an export intermediary, while the latter are less productive than producers which export directly. We show that the same sorting exists on the import side. By considering firms involved in both exporting and importing activities, we also find that direct two-way traders are on average more productive than firms trading indirectly on one of the two trade sides. The latter are in turn more efficient than indirect two-way traders. Finally, we investigate the effects of source-country characteristics on the sorting of firms into different modes of international trade.     

Trends and Drivers in CSR Disclosure: A Focus on Reporting Practices in the Automotive Industry

This work focuses on corporate social responsibility (CSR) disclosure practices of multinational corporations. Based on a longitudinal study of CSR reports of companies operating in the automotive industry, the paper offers a detailed study of how disclosure practices are changing and which principles and approaches influence and drive the development of such disclosure. Based on a four-year report-based study, the findings enable us to identify three main trends in the CSR disclosure strategy of automotive firms. First, in line with the mainstream CSR literature, the present study confirms the trend towards the increasing environmental and social accountability. Second, it adds evidence to the emerging debate regarding the harmonization and standardization of reporting and discusses this aspect by mentioning the standards as exerting some normative pressures within the sector. Finally, it provides evidence on specific links emerging between issues and actors. The implications of this evidence contribute to opening up the debate on CSR disclosure to the possibility of combining the institutional lens with a strategic approach that captures the materiality considerations of CSR disclosure.
