This paper examines the dynamic processes of agricultural land use in the context of the von Thünen model. Consumers purchase agricultural goods to maximize their utility levels; farmers plant agricultural goods only once in a year and they decide their land use according to the last year's prices. In this context, it is first shown that land use is generally unstable for a broad class of utility functions, although the equilibrium land use is achieved in a very specific case. Second, it is shown that under a certain condition, land use changes cyclically with 2-year intervals.  相似文献

In this paper we consider a continuous time model for the security price with the time-dependent volatility. It is shown that the non-normality and non-linear dependency of the short-term return, the major characteristics observed on many financial assets, can be incorporated into our model. In order to evaluate the option price formula on the model we propose a nonparametric predictor for the volatility function without reference to a specific functional form. We examine the so-called continuous record asymptotics and show that the proposed predictor is asymptotically minimax for a wide class of the volatility functions. One of the most important results is that the application of the Black-Scholes method can be justified by plugging the proposed predictor in the standard Black-Scholes formula even if the volatility changes over time.  相似文献

A recent study proposed an estimation approach that uses data on the independent variables and location for the prediction sample, and suggested that it may improve estimation and prediction. This is an incomplete data approach following an iterative process along the lines of the EM algorithm. The present study compares this approach with a partial data approach that uses only data on the dependent and independent variables and location for the estimation sample. Our Monte Carlo experiments show that unless the estimation and prediction samples constitute the whole population and the data generating model is used as the data fitting model, the incomplete data approach is not guaranteed to be superior to the partial data approach.  相似文献

This paper investigates how exchange rates affect Japanese exports. This is difficult because many of Japan's exports are used to produce goods for re-export. An appreciation in the importing country that decreases exports can decrease its imported inputs from Japan. To avoid this bias we examine consumption exports. Using a panel dataset of Japan's consumption exports to 17 countries over the 1988–2009 period, we find exchange rate elasticities of about one. These results indicate that the large swings in the value of the yen over the last decade have caused large swings in the volume of Japanese exports.  相似文献

ABSTRACT

This study highlights the importance of founders’ human capital on firms’ absorptive capacity for explaining the external knowledge sourcing (licensing-in and joint R&D) of start-up firms, using panel data from original questionnaire surveys conducted in Japan. The results of a probit model with an endogenous regressor show that firms managed by founders with a high level of specific human capital, measured as prior innovation experience and industry-specific work experience, tend to engage in external knowledge sourcing because of their superior absorptive capacity. The findings indicate that this type of human capital also promotes research and development (R&D) investment. Contrariwise, this study finds that firms managed by founders with a high level of general human capital, measured as educational attainment, tend to invest more in R&D, which enhances their absorptive capacity and thereby promotes external knowledge sourcing. Finally, the implications of these findings are discussed from the perspective of public policy.  相似文献

The recent financial crisis has highlighted the inadequacy of present supervisory arrangements to identify reliable ex‐ante indicators of banking distress. For a sample of US bank holding companies, we analyse the extent to which distance to default based on market data can be explained using accounting‐based indicators of risk. We show that a larger number of bank fundamentals help predict default for institutions that issue subordinated debt. For banks that issue sub‐debt, we find that higher charter values and low bank capitalizations further increase the power of bank fundamentals to predict default risk.  相似文献

We introduce a very fundamental and important axiom of the non-dummy. This states that each agent can change the outcome of the mechanism at some preference profile, thus guaranteeing every agent the minimum right to affect the social decision. We study the possibility of strategy-proof, efficient and non-dummy mechanisms in pure exchange economies. We provide two new interesting classes of such mechanisms. The results shed light on the structure of strategy-proof and efficient mechanisms, and should promote a complete characterization of those mechanisms in pure exchange economies with three or more agents.  相似文献

Scholars have compared and contrasted commercial and social entrepreneurship along a variety of dimensions, suggesting that entrepreneurial antecedents and outcomes differ within a social context. However, little is known about whether entrepreneurial processes differ within social contexts. In this paper, we ask to what extent the antecedents and outcomes that make social entrepreneurship unique influence entrepreneurial processes. Using an inputs–throughputs–outputs framework, we assess the relationship between four antecedents (social mission/motivation, opportunity identification, access to resources/funding, and multiple stakeholders) and three outcomes (social value creation, sustainable solutions, and satisfying multiple stakeholders) to the dimensions of entrepreneurial orientation (innovativeness, proactiveness, risk-taking, competitive aggressiveness, and autonomy) (Lumpkin and Dess, Acad Manag Rev 21(1):135–172, 1996). Our analysis suggests that many entrepreneurial processes remain essentially the same or are affected only slightly. However, autonomy, competitive aggressiveness, and risk-taking are influenced to some extent by the presence of multiple stakeholders and access to resources/funding. Entrepreneurial processes may also differ when applied to efforts to satisfy multiple stakeholders and achieve sustainable solutions. We subsequently discuss the implications of our analysis for future social entrepreneurship research and practice.  相似文献

In recent years, the success of Japanese firms in the global market has prompted efforts to understand the sources of their competitive advantage. It has been suggested that one such source is the Japanese firms' management accounting systems, and a number of articles have claimed that important differences do exist between U.S. and Japanese firms in this area. However, these claims have tended to be supported by anecdotal, rather than systematic, evidence. The objective of this article is to contribute further insights into similarities and differences between U.S. and Japanese firms' management accounting practices. Exhaustive searches of published surveys in the U.S. and Japanese literatures (much of which is in Japanese) provided the basis for U.S.-Japan comparisons on six aspects of management accounting practices. In turn, these comparisons were used for deriving implications for future research. Two major limitations of extant research and, thus, directions for future research are identified. First, future research needs to go beyond the simple use or non-use of techniques to investigate more detailed aspects of technique use. Second, since management accounting is only one component of a firm's total management system, attention also needs to be devoted to the organizational context, process, and goals of a firm's management accounting practices.  相似文献
