Free trade agreements and world obesity

We study the causal link between trade openness via free trade agreements (FTAs) and obesity rates. When applying a difference-in-differences approach by exploiting the year a country entered a free trade agreement with the United States during the period 1990–2016. We find a positive and causal impact of FTAs on obesity rates, which are statistically and economically significant. We show that our findings are robust to placebo tests, the use of synthetic control methods, and a maximized sample. Furthermore, we show that when using an event studies approach the equal trends assumption holds.     

Do good institutions improve fiscal transparency?

We study the role of institutional quality on the fiscal transparency of a country. We show that such a link does exist even when controlling for endogeneity. Our findings are robust to changes in specification and a host of transparency sub-measures. An advantage of our study is that we use new data on fiscal transparency for a cross-section of 82 countries, which are based on in-depth reports based on a standardized methodology and protocol. Furthermore, the fiscal measures were obtained with the collaboration of government authorities, which makes them particularly reliable.     

The Influence of Technology Differences on Corporate Environmental Patents: A Resource‐Based Versus an Institutional View of Green Innovations

This paper proposes that both the resource‐based view and institutional theory predict a positive relationship between the number of patented environmental innovations and non‐environmental innovations held by a firm, because they both are subject to the influence of similar factors. However, while the resource‐based view predicts that technological differences between the patented environmental innovations owned by a firm and those in the industry as a whole will positively affect the firm's environmental innovations, the institutional perspective predicts a negative relationship. Our results derive from a sample of 5537 environmental patents from 59 large companies in the electrical components and equipment industry worldwide, and show a positive relationship between patented environmental and non‐environmental innovations in a firm, but a negative influence on the number of the firm's patented environmental innovations resulting from differences between the firm's environmental technologies and those generally prevalent in the industry.

The theoretical and empirical fragilities of the expansionary austerity theory

Criticism to expansionary austerity theory has extensively addressed the methodological problems affecting the econometric techniques that underpin it; however, few efforts have formally analyzed its theoretical strictures. In this article, the authors develop a more general and comprehensive critique, both from a theoretical and from an empirical perspective. They first present a short-run model that formally describes the theoretical background of specific policy measures advocated by expansionary austerity supporters. They show how these measures might only have expansionary outcomes under extreme and unrealistic conditions. The authors then move to the data and provide an econometric analysis of the key variables that leave the results of our theoretical model undetermined; their findings reinforce the validity of our theoretical critique. Since 2007, when an important opportunity to test expansionary austerity presented itself with the recession, the core mechanisms of expansionary austerity theory seem to not have been working, to say the least. In fact, austerity measures delivered perverse results precisely in the countries where they were expected to be most effective.     

Formation and persistence of oppositional identities

We develop a dynamic model of identity formation that explains why ethnic minorities may choose to adopt oppositional identities (i.e. some individuals may reject or not the dominant culture) and why this behavior may persist over time. We first show that the prevalence of an oppositional culture in the minority group cannot always be sustained in equilibrium. Indeed, because the size of the majority group is larger, there is an “imposed” process of exposition to role models from the majority group that favors the diffusion of mainstream values in the minority community. In spite of this, an oppositional culture in the minority group can nevertheless be sustained in steady state if there is enough cultural segmentation in terms of role models, or if the size of the minority group is large enough, or if the degree of oppositional identity it implies is high enough. We also demonstrate that the higher the level of harassment and the number of racist individuals in the society, the more likely an oppositional minority culture will emerge. We finally show that ethnic identity and socialization effort can be more intense in mixed rather than segregated neighborhoods.     

Dividends and Market Signalling: an Analysis of Corporate Insider Trading

This study tests the multiple‐signal theory of dividends of John and Lang (1991) in the context of a European market. Our evidence shows that investors are more sensitive to insider trading signals than to signalled changes in existing dividends. In effect, the insider sales signal is universally understood as bad news. After controlling for the quality of a firm's investment opportunities, investors are found to penalise dividend outflows by mature firms that exhibit more informed insider sales activity. Finally, we offer an innovative exploration of the role of earnings announcements in market reaction to the dividend signal.     

Is technological change really skill‐biased? Evidence from the introduction of ICT on the Italian textile industry (1980–2000)

This paper investigates the effects of the introduction of information and communication technologies (ICT) on the skills of a workforce. Using micro-data collected from workers in the textile sector, we analyse whether the introduction of ICT has modified workers' tasks, so that higher skills and longer training periods than before are necessary. Empirical evidence suggests that the adoption of ICT has no universal skill-biased effect for all occupations at least in the textile sector.
