Intergenerational justice when future worlds are uncertain

Let there be a positive (exogenous) probability that, at each date, the human species will disappear. We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under this uncertainty, with expected-utility preferences. Various social welfare criteria entail alternative von Neumann Morgenstern utility functions for the EO: utilitarian, Rawlsian, and an extension of the latter that corrects for the size of population. Our analysis covers, first, a cake-eating economy (without production), where the utilitarian and Rawlsian recommend the same allocation. Second, a productive economy with education and capital, where it turns out that the recommendations of the two EOs are in general different. But when the utilitarian program diverges, then we prove it is optimal for the extended Rawlsian to ignore the uncertainty concerning the possible disappearance of the human species in the future. We conclude by discussing the implications for intergenerational welfare maximization in the presence of global warming.     

Testing the Null of Cointegration with Structural Breaks*

We propose a Lagrange Multiplier‐type statistic to test the null hypothesis of cointegration allowing for the possibility of a structural break, in both the deterministic and the cointegration vectors. Our proposal focuses on the presence of endogenous regressors. The test complements the usual non‐cointegration tests so as to obtain stronger evidence of cointegration. We consider the cases of known and unknown dates of the break. In the latter case, we show that minimizing the Sum of Squared Residuals results in a super‐consistent estimator of the break fraction. Finally, the behaviour of the tests is studied through Monte Carlo experiments.     

The shrinking endogeneity of optimum currency areas criteria: Evidence from the European Monetary Union—A beta regression approach

The endogeneity of optimum currency area criteria has been widely studied. Literature suggests the existence of a positive relationship between trade intensity and business cycle correlation. Using a beta regression model for the Eurozone we have concluded that trade has a decreasing marginal effect on business cycle correlation.     

Land consolidation in inland rural Galicia, N.W. Spain, since 1950: An example of the formulation and use of questions, criteria and indicators for evaluation of rural development policies

This paper examines whether the land consolidation (LC) practised since the 1950s in Galicia, N.W. Spain, has had the desired effects. To achieve this aim, we have adopted the methodology drawn up by the European Union for evaluation of its socioeconomic programmes, and we have adapted it as required by the subject matter and by the long-term historical perspective of this study. Our results suggest that, during the study period, LC has in general made a positive contribution to slowing rural depopulation.     

Migrant human and political capitals value in entrepreneur enterprise performance. A comparative study of four emerging markets

This paper investigates the impact of human and political capitals of entrepreneurs on enterprise performance in four emerging nations.The rent generation potential of these capitals is a well established fact, however, much less is known concerning the contingent nature of their value creation prowess. In this work, we draw on institutional theory and dynamic managerial capabilities perspective to examine the interactive effect of country of origin economic developement level and the international experience of entrepreurs, on the capitals, with respect to a set of financial indicators. Employing a quantitative methodology, our findings reveal that the relationship between the capitals and enterprise performance are indeeed contingent with the capitals of home-grown entrepreneurs, rather than those of returnee migrant entrepreneurs, exhibiting a greater propensity to influence enterprise performance. We conclude with implications for theory and practice.

     

Joined-up Government of utilities: a meta-review on a public–public partnership and inter-municipal cooperation in the water and wastewater industries

Private-sector participation in public services delivery has been criticized due to unfulfilled expectations. In response, joined-up government is being introduced as an alternative approach to providing water and wastewater services. This approach involves the establishment of horizontal (i.e. inter-municipal cooperation) and vertical (i.e. public–public partnership) integration. Drawing on a meta-review focused on the water and wastewater industries, this study shows that both arrangements have positive aspects, such as cost savings. However, contractual schemes and inter-departmental coordination efforts must be carefully managed or they will fail. In addition, research on cooperation between public bodies is scarce and must be better coordinated concerning study aims and methods.     

Technological advances and the decision to invest

Technological advances impact a firm’s investment decision, as they affect the investment cost. They can also affect the profitability due to demand shocks. We study a firm’s optimal investment decision when technological advances occur as surprises and induce uncertain reductions in the investment cost and in earnings. Despite this complex setting we derive closed-form solutions for the investment option value and the investment threshold. When technological advances only impact the investment cost, we demonstrate significant contributions compared to existing research, which restricts the analysis by keeping the expected investment cost path constant. For example, we show that, albeit the investment threshold is constant, the option value is very sensitive in the expected impact of technological advances. Leaving the restrictive setting, we obtain more intuitive results, e.g. that more frequent technological advances increase the option value. When technological advances impact future earnings we find important long-term effects: the investment threshold increases, whereas the option value decreases. Finally, earnings volatility postpones investment, while uncertainty due to technological advances expedites investment.     

Farmers,institutions and technology in agricultural change processes: outcomes from Adaptive Research on rice production in Sulawesi,Indonesia

International agricultural research centres use approaches which aim to create effective linkages between the practices of farmers, introduced technologies and the wider environment that affects farming. This paper argues that such new approaches require a different type of monitoring as a complement to conventional approaches that tend to favour a quantitative assessment of adoption and impact at the farm level. In this context, we examined monitoring data from an Adaptive Research (AR) project highlighting complementary qualitative analysis. Our emphasis is to capture the improvisational capacities of farmers and to reveal social and institutional constraints and opportunities in a broader innovation system. Our approach provided clear insights into how rice farmers adjusted their practices and how actors involved linked (or not) with others in the innovation system. We also demonstrated how institutions such as policies, religious rituals or service provider arrangements pose conditions that establish or constrain practices aligned with introduced technologies. A broader perspective in monitoring AR therefore provides important additional insights into the factors which shape outcomes in farming communities. To expand outcomes, AR projects should also pay attention to designing and testing new institutional arrangements that create enabling conditions for agricultural innovation.     

Small‐scale technologies and European coal mine safety, 1850–1900

This article considers new technologies and fatal accident rates in European coal mining from 1850 to 1900. Its contributions are twofold: to recover and emphasize improvements in small‐scale mine technologies such as safety lamps and ventilation, and, second, to deny any role at this time for later macroinventions such as electrification and mechanization. We discuss the influence of these safety‐improving technologies as well as government regulations on different kinds of fatal accident rates. It is proposed that an important and overlooked source of the reduction in fatalities from certain kinds of accidents was the introduction and diffusion of a variety of safety‐related technologies, none of particularly large scale.
