Reassessing the productivity gains from trade liberalization

This paper reassesses the impact of trade liberalization on productivity. We build a new, unique database of effective tariff rates at the country‐industry level for a broad range of countries over the past two decades. We then explore both the direct effect of liberalization in the sector considered, as well as its indirect impact in downstream industries via input linkages. Our findings point to a dominant role of the indirect input market channel in fostering productivity gains. A 1 percentage point decline in input tariffs is estimated to increase total factor productivity by about 2 percent in the sector considered. For advanced economies, the implied potential productivity gains from fully eliminating remaining tariffs are estimated at around 1 percent, on average, which do not factor in the presumably larger gains from removing existing non‐tariff barriers. Finally, we find suggestive evidence of complementarities between trade and FDI liberalization in boosting productivity. This calls for a broad liberalization agenda that cuts across different areas.     

The diffusion of a new telecommunication service : Network constraints and service quality in a dynamic interpretative model

In this paper, a discrete time model for the adoption of a new telecommunication service is proposed. We analyze the interaction of three sets of agents involved in the process: users, information providers, and network providers. We consider the effects of the network constraint and of the expectations of the users and suppliers.

Impact of social media on economic growth – evidence from social media

This article attempts to investigate the impact of social media (SM) on economic growth. Using information obtained from memberships to social networks, we find that SM has a negative and significant impact on economic growth. This provides evidence in favour of our hypothesis that SM increases the search costs for information and also increases the substitution effect from labour to leisure thereby producing a negative impact on growth.     

Euro money market spreads during the 2007–? financial crisis

In the paper we investigate the empirical features of euro area money market turbulence during the recent financial crisis. By means of a novel Fractionally Integrated Heteroskedastic Factor Vector Autoregressive model, we find evidence of a deterministic level factor in the EURIBOR-OIS (OIS) spreads term structure, associated with the two waves of stress in the interbank market, following the BNP Paribas (9 August 2007) and Lehman Brothers (16 September 2008) “shocks”, and two additional factors, of the long memory type, bearing the interpretation of curvature and slope factors, respectively. The unfolding of the crisis yields a significant increase in their persistence and volatility. We also find evidence of a declining trend in the level and volatility of OIS spreads since December 2008, associated with ECB liquidity policies.     

Detecting the relationship between competitive intensity and firm product line length: Evidence from the worldwide mobile phone industry

The way firms lengthen or shorten their product line with respect to rivals is regarded as one of the possible strategies firms can pursue to respond to competition. This article builds and tests hypotheses to study the effect of different levels of competitive intensity on product line length. The empirical analysis of data on 3,527 handset models introduced by 66 mobile phone vendors from 1994 to 2010 shows a consistent inverse U‐shaped relationship between competitive intensity and the firm's product line length. In this way, we pinpoint an interesting link between the product line extension literature and the competitive dynamics and competitive intensity perspectives.

STUDYING INEQUALITY IN INCOME DISTRIBUTION OF SINGLE-PERSON HOUSEHOLDS IN FOUR DEVELOPED COUNTRIES

The increasing frequency of single-person households has become a major economic phenomenon, and is likely to become an important political force. This paper focuses on differences related to inequality of income distribution among single-person households in Europe's four largest economies, i.e. France, Germany, Italy and the U.K. Income distribution was modeled in terms of individual characteristics using a parametric model with heterogeneous model parameters. Poverty differences were also broken down using the results of Biewen and Jenkins (2005 ) in order to understand the relationship between poverty and individual characteristics among countries.     

The “Bologna Process” and college enrollment decisions

We use survey data on high school graduates before and after the Italian reform of tertiary education implementing the “Bologna Process” to estimate its impact on college enrollment. Individuals leaving school after the reform have a probability of enrollment that is 15% higher compared to otherwise identical individuals. This increase is concentrated among individuals with good school performance and low parental background. We interpret this result as an indication of the existence of constraints – for good students from less advantaged households – on the optimal schooling decision. We also find a small negative impact of the reform on university drop-out.     

Growth with Unused Capacity and Endogenous Capital Depreciation

The paper contributes to the debate on growth and distribution in a non‐mainstream perspective. It looks at the role that capacity utilization plays in the process of growth under the hypothesis that the rate of capital depreciation is a function of the degree of capacity utilization. Our hypothesis implies results partly different from those obtained by other models in which capacity utilization plays a key role. In particular, a varying rate of depreciation affects the conditions under which distributional changes in favor of wages affect the rate of growth positively.
