Dairy productivity and climatic conditions: econometric evidence from South‐eastern United States

Climate change and food security have become critical issues in the agricultural policy agenda. Although global warming is expected to increase both the frequency and severity of heat stress on dairy cattle, there are very few economic studies focusing on this issue. This paper contributes to the literature by integrating the frontier methodology, commonly used in applied production economics, with heat stress indexes used by animal scientists but largely ignored by economists. Our econometric models are useful to quantify gross benefits expected from adaptation to climatic conditions represented by the Temperature Humidity Index (THI) and alternatively by the Equivalent Temperature Index (ETI). Stochastic production frontier analysis is used to measure technical efficiency for an unbalanced panel of 103 dairy farms located in Florida and Georgia. Five alternative model specifications are evaluated. The results reveal that both THI and ETI have a significant nonlinear negative effect on milk production. The climatic indexes when incorporated in the frontier specification absorb some of the output shortfall that otherwise would be attributable to inefficiency. The results indicate that using fans combined with sprinklers is an effective adaptation to offset output losses stemming from heat stress conditions.     

Impact of firm heterogeneity on direct and spillover effects of FDI: Micro-evidence from ten transition countries

This paper presents a comparative study of the importance of direct technology transfer and spillovers through FDI on a set of 10 transition countries, using a common methodology and appropriate methods to account for selection and simultaneity correction. This paper considers by far the largest firm level dataset (more than 90,000 firms) used by any study on the spillover effects of FDI. The main novelty of the paper is the explicit control for various sources of firm heterogeneity when accounting for different effects of FDI on firm performance. This work shows that the heterogeneity of firms in terms of absorptive capacity, size, productivity and technology levels affect the results. Controlling for these variables leads to some interesting results, which contrast with the previous empirical work in the field. We find that horizontal spillovers have become increasingly important over the last decade, and they may even become more important than vertical spillovers. Positive horizontal spillovers are equally distributed across size classes of firms, while negative horizontal spillovers seem to be more likely to accrue to smaller firms. Moreover, positive horizontal spillovers seem more likely to be present in medium or high productivity firms with higher absorptive capacities, while negative horizontal spillovers are more likely to affect low to medium productivity firms. These findings suggest that both direct effects from foreign ownership as well as the spillovers from foreign firms substantially depend on the absorptive capacity and productivity level of individual firms. In addition, these results show that foreign presence may also affect smaller firms to a larger extent than larger firms, but this impact may be in either direction.     

VISITORS' INTENTION TO VISIT WORLD CULTURAL HERITAGE SITES: AN EMPIRICAL STUDY OF SUZHOU,CHINA

This article attempts to study Chinese visitors' intention to visit world cultural heritage sites in the framework of the theory of planned behavior (TPB), with the additional constructs of past experience and cultural tour involvement. The survey data were collected by a self‐administrated questionnaire in Suzhou, which is one of the cities with world cultural heritage sites in China. Structural equation modeling was employed to test the research model and hypotheses. The result shows that perceived control, past experience, and cultural tour involvement, but not attitude and subjective norms, are valid predictor constructs for visitors' intention to visit a world cultural heritage site within the next 12 months. The findings have implications for predicting heritage tourism.     

Relational trust and new ventures’ performance: the moderating impact of national-level institutional weakness

This study investigates the link between relational trust in exchange partners and new venture performance, and determines whether weakness in national-level formal institutions influences this link. Based on a sample of 203 entrepreneurs and their new ventures from Germany and China, findings reinforce the idea that new venture performance may profit from relational trust in exchange partners. However, interaction analyses also reveal that the performance implications of relational trust are contingent on the institutional context. The contributions and implications of these findings are discussed.     

Comparing monetary policy reaction functions: ECB versus Bundesbank

This paper compares the European Central Bank’s (ECB) conduct of monetary policy with that of the Bundesbank. Estimated monetary policy reaction functions show that the ECB reacts similarly to expected inflation but significantly stronger to the output gap than the Bundesbank did. Theoretical considerations suggest that this stronger response to the output gap may rather be due to a higher interest rate sensitivity of the German output gap than to a higher weight given to output stabilisation in the objective function of the ECB. Counterfactual simulations based on the estimated interest rate reaction functions reveal that German interest rates would not have been lower under a hypothetical Bundesbank regime after 1999. However, this conclusion crucially depends on the assumption of an unchanged long-run real interest rate for the EMU period and is reversed when the Bundesbank reaction function is adjusted for the lower long-run real interest rate estimated for the ECB regime.

Knowledge diffusion and morality: Why do we freely share valuable information with Strangers?

This article offers a model integrating heterogeneously moral preferences to overcome the seemingly irrational tendency of individuals to freely share data and knowledge. We build on recent literature showing that moral preferences are favored by evolution theoretically, and have a strong explanatory power empirically, to model individual sharing behavior. Our analysis highlights the limit of financial incentives and the importance of promoting a sharing culture by enhancing awareness. Shedding light on how people respond not only to financial but also moral motives, we contribute to the ongoing policy debate on the design of effective open science policies.
