There has been remarkable growth in the number of studies using data envelopment analysis (DEA) in research on higher education. Heterogeneous DEA models have been applied in assessing the performance of higher education institutions (HEIs), and the multi-faceted production process of higher education has further motivated the extension and improvement of the DEA approach. The present study conducts a meta-regression analysis of 109 published DEA applications in higher education at different levels of analysis to provide a better understanding of the relationship between the efficiency results and the attributes of the studies implemented in different nations.  相似文献

We investigate the dynamic relationship between coffee exports and machinery imports in Brazil from 1869 to 1939. Our tests reveal cointegration and bidirectional causality in the temporal sense. This evidence suggests that foreign exchange real revenues from coffee exports were important for the onset of industrialization, as machinery imports proxy for real investment demand. Capital growth, in turn, also helped to boost the country’s exports.  相似文献

Scientific research in general and economics research in particular is a social act. More specifically, schools of economic thought as well as associations, research groups and conferences are expressions of social organizations within the realm of economics. Historically, studies investigating the methodologies used in economics have focused on the strengths of these social organizations. This study aims to analyze the key roles played by individuals within social organizations in building and reinforcing economics and, in turn, their influence on these individuals. To achieve this goal, we use an institutionalist approach in a broad sense. We show how economics as an academic environment can be presented as an institutional entanglement and how an institutionalist approach can enhance an understanding of why economists adopt a particular theoretical and methodological perspective. It is argued that habits, observations and cognitive abilities should be seriously considered to understand the logic and decision making of economic researchers. We discuss also the importance of forming groups in the process of institutionalizing elements relevant to an economic researcher’s logic and decision making and present an interpretation of mainstream economics in terms of the analytical approach of our study.  相似文献

Universities in Vietnam are inclined to have an inefficient mix of input resources because of rigidities restricting the adoption of advanced teaching technology. There has been a deferral of the adoption of new teaching technologies to meet the rest of the world's higher education standards. Using an input‐orientated data envelopment analysis (DEA) method, technical, scale and mix efficiency indicators are estimated for 112 Vietnamese universities over the period 2011–2013 using the Färe–Primont index. The results indicate that the technical, scale and mix efficiency indicators are 0.784, 0.866 and 0.829, respectively. Using the fractional regression model, it is found that location, age, ownership and financial capacity have significant influences on the mix efficiency indicators of universities.  相似文献

The presence of a slowdown in new product life cycles has recently received notable attention from many innovation diffusion scholars, who have tried to explain and model it on a dual-market hypothesis (early market-main market). In this paper we propose an alternative explanation for the slowdown pattern, a dual-effect hypothesis, based on a recent co-evolutionary model, where diffusion results from the synergy between two driving forces: communication and adoption. An analysis of the synergistic interaction between communication and adoption, based on the likelihood ratio order or on a weak stochastic order, can inform us of which of the two had a driving role in early diffusion. We test the model on the sales data of two pharmaceutical drugs presenting a slowdown in their life cycle and observe that this is identified almost perfectly by the model in both cases. Contrary to the general expectation, according to which communication should precede adoption, our findings show that adoptions may be the main driver in early life cycle; this may be related to the drug's specific nature.  相似文献

Using cross‐sectional farm‐level data from 3,164 rice‐farming households in the Philippines, we measure the impact of modern rice technologies on farm productivity while disentangling technology gaps (the distance between production frontiers) from managerial gaps (differences in technical efficiency). To do so, we combine a recently developed stochastic production frontier framework with impact evaluation techniques to control for biases stemming from observables and unobservables. First, we find an adequate control group using propensity score matching to mitigate the effect of biases from observable variables. Then, we test for biases that might arise from unobserved variables using a stochastic frontier framework corrected for self‐selection. Finally, we estimate meta‐frontiers to assess productivity differences between adopters and non‐adopters. The analysis shows that the adoption of certified seeds has a significant and positive impact on productivity, efficiency and net income in rice farming.  相似文献

Translated versions of the Miner Sentence Completion Scale-Form T and of the Differential Attribution Questionnaire were administered to entrepreneurs and to managers, in Israel, Northern and Southern Italy and Sweden. The results of this research yield strong support for a framework that integrates affective and cognitive motivational factors. In particular, it found: (1) that the way entrepreneurs deal with negative outcomes explains their perseverance and affects their self-achievement; (2) a risk-avoidance rather than a risk-taking preference distinguishes them; (3) Self-Achievement; Risk-Avoidance and Personal Innovation appear to be major components of Task Motivation. This research appears to move closer toward a more parsimonious and clearer understanding of the behaviour of the central figure in wealth formation, thus providing a framework for the designing of entrepreneurial development programmes.  相似文献

This paper analyzes the question of whether Ryanair's pricing strategies have changed over time. We create a panel dataset of fares for all of Ryanair's European flights over a two-year period, from 1 January 2006 to 31 December 2007. We calculate the average fare over a 90-day period prior to departure and the intensity of dynamic pricing for each flight in the panel, in particular analysing the changes in these variables observed between pairs of “equivalent” flights. Our results show that overall, both average fares and the intensity of dynamic pricing decreased in 2007. More than one-third of flights saw a price reduction of more than 10%. Now that it has become the dominant low-cost carrier in Europe, Ryanair appears to be softening its dynamic pricing activities on existing routes, typically employed to stimulate additional touristic demand. Thus, booking in advance becomes relatively more expensive.  相似文献
