Research collaboration has become an important characteristic of contemporary academia and is of prime importance for the academic career opportunities of young scholars. For the purposes of this study research collaboration is a formal manifestation of intellectual collaboration in scientific research and involves the participation of two or more authors in the production of a joint publication. The paper reports the findings of a quantitative online survey sent to tourism scholars to explore their career and collaboration patterns in co-authored publications in tourism research. The results indicate that there are divergent perspectives on research collaboration and that collaboration characteristics change as scholars progress through their careers. The paper proposes a research career lifecycle to explain the patterns in tourism research collaboration.  相似文献

Using online platforms to deliver educational content, some institutions have developed blended courses that combine the advantages of online instruction with traditional face-to-face (F2F) teaching. This study compares accounting student performance and satisfaction in two blended formats with similar content and design, i.e. F2F+ vs. Online+ courses. It also assesses the characteristics of students who choose the latter option over F2F+ courses. Students in four advanced accounting subjects were surveyed and their course performance was obtained. Results indicate that the main determinants of students’ decision to register for an Online+ course are retaking the course, increased weekly work hours, and belief that this type of blended course facilitates learning. Results show that students in advanced accounting courses with equivalent content and design perform similarly and have the same level of course satisfaction across course delivery formats, as hypothesized under equivalency theory.  相似文献

Demand uncertainty is thought to influence irreversible capacity decisions. Suppose that local demand can be sourced from domestic (rigid) production or from (flexible) imports. This paper shows that the optimal domestic capacity is either increasing or decreasing with demand uncertainty, depending on the relative level of the costs of domestic production and imports. We test this relationship with data from the U.S. cement industry, in which the difference in marginal cost between domestic production and imports varies across local U.S. markets because cement is costly to transport over land. Industry data for 1999 to 2010 are consistent with the predictions of the model. The introduction of two technologies to the production set—one rigid and one flexible—is crucial to understanding the relationship between capacity choice and uncertainty in this industry because there is no relationship between these two variables in aggregated U.S. data. Our analysis reveals that the relationship is negative in coastal districts, and significantly more positive in landlocked districts.  相似文献

We develop a closed form formula for the value of a fixed-rate residential mortgage that includes the provision that the borrower can prepay at any time with no penalty. The value of the mortgage equals the expectation, under the risk neutral probability measure, of the future cash flows. We model future cash flows by estimating an empirical model of prepayment behavior. A second change of measure leads to a closed form expression for the expectation. The closed form values explain most of the time series variation in MBS prices. The closed form formula significantly shortens the time to calculate mortgage values and durations and can be a useful tool for portfolio management and hedging.  相似文献

We present a model of vertical contracts between manufacturers and retailers with nonlinear pricing strategies. Using home‐scan data on bottled water produced by manufacturers and sold by retail chains in France, we estimate a structural demand and supply model allowing for two‐part tariff contracts between manufacturers and retailers. Using price‐cost margins recovered from estimates of demand parameters, we select the best supply model by performing nonnested tests, and find that manufacturers use two‐part tariff contracts with resale price maintenance. We then perform counterfactual policy simulations that restrict the use of these vertical contracts and assess welfare effects under alternative scenarios.  相似文献

This study looks at international competitiveness of agriculture in the European Union and the United States. The most intuitive concept is that of price competitiveness. We calculate relative prices for 11 member states of the European Union and the United States for the period 1973–2002. We assume that markets are perfectly competitive and in long‐run equilibrium, so that the observed price always equals average total cost, as measured by the cost dual to the production function. This assumption is used in our calculation of relative competitiveness and productivity gaps between the European Union and the United States and in our decomposition of relative price movements between changes in relative input prices and changes in relative productivity levels.  相似文献

This paper uses data from one of the most important European stock markets and shows that, in line with predictions from theoretical market microstructure, a small number of latent factors captures most of the variation in stock specific order books. We show that these order book commonalities are much stronger than liquidity commonality across stocks. The result that bid and ask side as well as the visible and hidden parts of the order book exhibit quite specific dynamics is interpreted as evidence that open order book markets attract a heterogeneous trader population in terms of asset valuations and impatience. Quantifying the informational content of the extracted factors with respect to the evolution of the asset price, we find that the factor information shares are highest (about 10%) for less frequently traded stocks. We also show that the informational content of hidden orders is limited.

This paper provides a selective review of the recent analytical and empirical literature on the benefits and costs of international financial integration. It discusses the impact of financial openness and capital flows on consumption, investment and growth, as well as the impact of foreign bank entry on the domestic financial system. It argues that, for small open developing countries, the benefits of financial integration are mostly long term in nature, whereas risks can be significant in the short run. Careful preparation and management are therefore essential to ensure that short‐run costs do not lead to policy reversals. It also stresses that the empirical evidence on the impact of foreign direct investment on domestic capital formation and growth, as well as on the effects of foreign bank entry, should be viewed with caution. In particular, the possibility that foreign bank penetration may lead to adverse changes in the allocation of credit cannot be dismissed on the basis of the existing evidence.  相似文献
