The effects of technology shocks on hours and output: a robustness analysis

We analyze the effects of neutral and investment‐specific technology shocks on hours and output. Long cycles in hours are removed in a variety of ways. Hours robustly fall in response to neutral shocks and robustly increase in response to investment‐specific shocks. The percentage of the variance of hours (output) explained by neutral shocks is small (large); the opposite is true for investment‐specific shocks. ‘News shocks’ are uncorrelated with the estimated technology shocks.

Effects of redistributing policy support on farmers’ technical efficiency

The objective of this article is twofold: first, investigating the relationship between technical efficiency and decoupled direct payments of a sample of Italian farms prior to the application of the 2014–2020 Common Agricultural Policy reform; second, evaluating possible implications of alternative scenarios about distribution of direct payments on technical efficiency. To these aims, a stochastic frontier analysis is adopted. Results indicate that direct payments produce significant effects on technical efficiency in specialized farms, which received higher levels of support. However, effects are contrasting. Moreover, results show that redistribution of policy subsidies may negatively impact on technical efficiency to an extent depending upon the criterion of redistribution applied. Finally, some policy suggestions are given.     

Transatlantic Trade-Offs in the Age of Balanced Budgets and European Monetary Union

We develop a model of monetary and fiscal policies appropriate for considering U.S.-European policy interactions in an era of near-balanced budgets and European monetary union. We study the determinants of policy trade-offs and incentives for central banks and governments across the Atlantic. Smaller, more open economies face more favorable trade-offs, since openness enhances policy effectiveness via the exchange-rate channel. Changes in Europe's monetary arrangements do not affect U.S. trade-offs, although they alter the trade-offs facing European policy-makers. Fiscal trade-offs depend crucially on the extent to which fiscal policy is distortionary. Changes in taxes and spending move both employment and inflation in the desired direction following a worldwide supply shock when spending is financed with distortionary taxes.     

Testing for the Presence of Financial Constraints in US Agricultural Cooperatives: An Investment Behaviour Approach

This study examines the presence of financial constraints in US agricultural cooperatives. We test the cooperative capital constraint hypothesis with a panel data econometric analysis of agricultural cooperatives’ investment behaviour. Regression results suggest that agricultural cooperatives’ capital expenditures are significantly affected by the availability of internal funds. Results also indicate that the sensitivity of investment to cash flow is correlated with cooperative structural characteristics.     

On Markov error‐correction models,with an application to stock prices and dividends

This paper considers Markov error‐correction (MEC) models in which deviations from the long‐run equilibrium are characterized by different rates of adjustment. To motivate our analysis and illustrate the various issues involved, our discussion is structured around the analysis of the long‐run properties of US stock prices and dividends. It is shown that the MEC model is flexible enough to account for situations where deviations from the long‐run equilibrium are nonstationary in one of the states of nature and allows us to test for such a possibility. An empirical specification procedure to establish the existence of MEC adjustment in practice is also presented. This is based on a multi‐step test procedure that exploits the differences between the global and local characteristics of systems with MEC adjustment. Copyright © 2004 John Wiley & Sons, Ltd.     

Certainty Independence and the Separation of Utility and Beliefs

Economists often operate under an implicit assumption that the tastes of a decision maker are quite stable, while his beliefs change with the availability of new information. We show that for a general class of preferences, a separation of a key component of tastes, the utility function, from the other components of the representation is possible only if the decision maker's preferences satisfy a mild but not completely innocuous condition, called ‘certainty independence’. We also outline the axiomatic characterization of the preferences that obtain such separation, which are a subset of the biseparable preferences.     

Social cooperatives,social welfare associations and social networks

We use an original data-set to study how participation in two types of non-profit organizations – i.e. social welfare associations and social cooperatives – affects individual social capital, understood as a network of cooperative relationships. Participation in both the types of organization allows members to start new social relations. However, social welfare associations seem to play a significantly greater role in the development of volunteers’ social capital, favouring the creation of weak ties that are used to exchange information and advice, and offering the opportunity to establish stronger ties entailing concrete mutual support. Within social cooperatives, workers appear to develop their individual social capital to a greater extent than volunteers. Our results suggest that the composition of the workforce, the depth of members’ involvement in the organization’s activities and the human resources strategies adopted by the management influence the creation of cooperative relations through on-the-job interactions.
