THE INTERNATIONAL DIMENSION OF PRODUCTIVITY AND DEMAND SHOCKS IN THE US ECONOMY

This paper analyzes the cross‐country effects of productivity and demand disturbances in the United States identified with sign restrictions based on standard theory. Productivity gains in US manufacturing increase US consumption and investment vis‐à‐vis foreign countries, resulting in a trade deficit and higher international prices of US goods, despite the rise in their supply. Financial adjustment works via a higher global value of US equities, real dollar appreciation, and an expansion of US gross foreign liabilities as well as assets. Positive demand shocks to US manufacturing also increase investment and cause a real dollar appreciation, but have limited effects on the trade balance and net foreign assets. Our findings emphasize the importance for macroeconomic interdependence of endogenous fluctuations in aggregate demand across countries in response to business cycle shocks.     

Incomplete Contracts and Complexity Costs

This paper investigates, in a simple risk-sharing framework, the extent to which the incompleteness of contracts could be attributed to the complexity costs associated with the writing and the implementation of contracts. We show that, given any measure of complexity in a very general class, it is possible to find simple contracting problems such that, when complexity costs are explicitly taken into account, the contracting parties optimally choose an incomplete contract which coincides with the default division of surplus. Optimal contracts with complexity costs are constrained efficient in our model. We therefore interpret our results as saying that, in the absence of a strategic role for complexity costs, their effect is entirely determined by their size relative to the size of payoffs.     

Measuring Well-Being and Progress

Well-being is becoming a concept which is more and more involved in any world development consideration. A large amount of work is being carried out to study measurements of well-being, including a more holistic vision on the development and welfare of a country. This paper proposes an idea of well-being and progress being in equilibrium with each other. This is distant from the two extreme positions: poor but happy, and rich then happy; too romantic the first, and reductive the second. After a short explanation on the meaning of Objective and Subjective well-being, we show some interesting relations between economic and social variables, and we propose a new index to measure the well-being and progress of the countries: the Well-being & Progress Index (WIP). It includes several aspects of well-being and progress, like human rights, economic well-being, equality, education, research, quality of urban environment, ecological behaviours, subjective well-being, longevity, and violent crime. The most frequently used indexes usually only focus on some aspects, like ecology, or economy, or policy, or education, or happiness, and so forth. On the contrary, this new WIP index allows a global and well-balanced vision, thanks to the large range of indicators used, and how representative they are.     

Social workers' views on community involvement in child protection work in Italy

Involvement of the community is a topic that is gaining increasing importance in the debate on child protection social work. However, the empirical findings that help to understand the factors which enable social workers to involve community actors successfully are still scarce. The article presents the results of an empirical pilot study carried out on a sample of 24 child protection social workers employed in four public agencies in Italy. The results of the research highlight the complexity of the factors that influence the ability of social workers to involve the community in schemes involving children and their families and the importance of constructing a community‐based approach that directly involves local‐level institutions and policy programmes.     

CYCLICAL TAX ENFORCEMENT

We wonder whether tax enforcement varies along the economic cycle and aim at answering that question from a positive perspective by means of survey data for the Spanish case (1994–2015). According to a fiscal capacity argument, tax enforcement might be stronger in times of crisis (counter-cyclical), but if the tax administration prioritizes taxpayers' welfare over public revenue, enforcement might be slacker (procyclical). We find tax enforcement is not immune to the state of the economy. In particular, it presents a prevailing counter-cyclical trend, but in presence of a severe economic crisis it turns out to be procyclical. (JEL D78, H12, H26, H83)     

Subjective Beliefs and ex ante Trade

We study a definition of subjective beliefs applicable to preferences that allow for the perception of ambiguity, and provide a characterization of such beliefs in terms of market behavior. Using this definition, we derive necessary and sufficient conditions for the efficiency of ex ante trade and show that these conditions follow from the fundamental welfare theorems. When aggregate uncertainty is absent, our results show that full insurance is efficient if and only if agents share some common subjective beliefs. Our results hold for a general class of convex preferences, which contains many functional forms used in applications involving ambiguity and ambiguity aversion. We show how our results can be articulated in the language of these functional forms, confirming results existing in the literature, generating new results, and providing a useful tool for applications.

Internationalisation and outsourcing of operations and product development in the fashion industry

This paper investigates the choices in terms of internationalisation and outsourcing of operations and product development activities, as well as collaboration practices used within and across organisations, in different segments of the European fashion industry. Based on multiple, in-depth case studies from Italy, Germany and the UK, the paper shows that fashion companies adopt different configurations of operations and product development, i.e. integrated, collaborative and virtual, ranging from local-integrated models to global-full outsourcing of operations and product development activities. For each configuration, different collaboration practices are in use. Product line positioning and quality, firm size, sales volumes and technical complexity of the products are the key drivers determining the configuration choices and the adoption of certain collaboration practices.
