The performance of the British retail sectors in terms of productivity growth is not brilliant. This paper focuses on a specific component of productivity growth (technical efficiency) and tests the extent to which its variance across the sector can be explained by the differences in the educational attainment of the pool of workers to which retail firms have access. The empirical analysis is carried out on a sample of 1061 retail firms from the Annual Respondents Database, 1997–2005. The results confirm that the county-level differences of the stock of human capital can explain the technical efficiency differentials across the sector. 相似文献

In this paper, we aim to fill the gap in the banking literature by quantifying the impact that the Schumpeterian competition mode – i.e. competition through the launch of new products (or new varieties of products) – has on the cost and profit efficiency of a sample of commercial banks based in the United Kingdom. We estimate both a cost and an alternative profit frontier on an unbalanced panel of UK commercial banks over the period 2001–2012. The intensity of competition through product innovation is proxied by the trademark intensity (i.e. the ratio between the number of trademarks registered in a given year by all the commercial banks – net of the trademarks registered by the bank under observation – and the employment in the sector) in the commercial banking sector. Our results show that the (lagged) trademark intensity in the commercial banking sector does affect negatively the mean cost and profit efficiency in the sector but there is evidence that as trademark intensity increases in the sector, commercial banks react by improving their cost and profit efficiency. 相似文献

This paper analyzes the diffusion of internet-based distance education technology (NETDE) among the US associate colleges. The study finds that an institution with experience in using an earlier generation distance education technology is more likely to adopt NETDE than an institution without such an experience. The finding supports the view of Cohen and Levinthal (1990) that an organization's ‘absorptive capability’ plays a significant role in its innovative activities. Institution size also facilitates the adoption of NETDE. We relate this size effect to market power because the size effect is partly caused by customer switching costs present in the NETDE market. Finally, we find that, among public institutions, the presence of close competitors motivates an institution to adopt NETDE earlier. 相似文献

In this article, we examine the degree of persistence in monthly real exchange rate of six East Asian countries in relation to their two major trading partners, the United States and Japan, to study the validity of PPP for the 1976:01–2009:03 period. To investigate the persistency in real exchange rate series, we use sum of the autoregressive (AR) coefficients and the confidence interval for it using grid-bootstrap procedure recently developed by Hansen (1999). We have two findings: first, we find evidence for high persistency in real exchange rate in terms of the Japanese yen for five countries and for four countries in terms of the US dollar the for the full and pre-crisis sample periods. Second, for the post-crisis period, the presence of low persistency in real exchange rate supports PPP for three countries in terms of the Japanese yen and five countries in terms of the US dollar. These findings indicate that real exchange rate series of five East Asian countries are mean-revert based on their exchange rate policies and East Asian countries can form a currency union. 相似文献

ABSTRACTWe use an extended version of the well-established Crepon, Duguet, and Mairesse model [1998. “Research, Innovation and Productivity: An Econometric Analysis at the Firm Level.” Economics of Innovation and New Technology 7 (2): 115–158] to model the relationship between appropriability mechanisms, innovation, and firm-level productivity. We enrich this model in three ways: (1) We compare estimates obtained using a broader definition of innovation spending to those that use R&D spending. (2) We assume that a firm simultaneously innovates and chooses among different appropriability methods to protect the innovation. (3) We estimate the impact of innovation output on firm productivity conditional on the choice of appropriability mechanism. We find that firms that innovate and rate formal methods for the protection of intellectual property highly are more productive than other firms, but that the same does not hold in the case of informal methods of protection, except possibly for large firms as opposed to SMEs. We also find that this result is strongest for firms in the services, trade, and utility sectors, and negative in the manufacturing sector. 相似文献

The causal link between tourism receipts and GDP has recently become the major focus of some recent studies in tourism economics. Results obtained in these studies about the causal link appear to be sensitive with respect to the countries analyzed, sample period and methodology employed. Considering the sensitivity of the causal link, we use the rolling window and time-varying coefficients estimation methods to analyze the Granger causality based on Vector Error Correction Model (VECM). When applied to Turkey for the 1963–2006 periods, this methodology enables us to overcome differences in the outcome of the tests performed in other studies for tourism receipts and GDP. The findings of this paper are as follows: results from the full sample within the VECM model indicate that there is no Granger causality between the series, while the findings from the time-varying coefficients model based on the state-space model and rolling window technique show that GDP has no predictive power for tourism receipts; however, tourism receipts have a positive–predictive content for GDP following early 1980s. 相似文献

Public discussions of ethical issues related to the biotechnology industry tend to treat “biotechnology” as a single, undifferentiated
technology. Similarly, the pros and cons associated with this entire sector tend to get lumped together, such that individuals
and groups often situate themselves as either “pro-” or “anti-” biotechnology as a whole. But different biotechnologies and
their particular application context pose very different challenges for ethical corporate decision-making. Even within a single
product category, different specialty products can pose strikingly different ethical challenges. In this paper, we focus on
the single over-arching category of “genetic testing” and compare tests for disease susceptibility and drug response. We highlight
the diversity of ethical challenges – grouped under the broad categories of “truth in advertising” and “protecting intellectual
property” – raised by the commercialization and marketing of these technologies. By examining social and technical differences
between genetic tests, and the associated corporate ethics challenges posed by their commercialization, our intent is to contribute
to the nascent business ethics literature examining issues raised by the development and marketing of genetic tests.

ABSTRACTThis article tries to reconcile two major priorities for countries, notably resource-rich countries on the international development agenda: export product diversification with a view to helping them better integrate into the multilateral trading system and tax reforms with a view to reducing the dependence of total public revenue on resource revenue, and therefore developing a more sustainable stream of public revenue. The analysis therefore involves examining empirically the impact of export product diversification on countries’ overall public revenue dependence on resource revenue, this dependence being measured by the share of resource revenue in total public revenue. The empirical analysis shows that export product diversification exerts a negative and significant impact on resource revenue share of total public revenue, and therefore could help facilitate tax reforms towards lower resource revenue dependence. Hence, while tax policy is the main policy tool to conduct tax reforms, export product diversification would likely contribute to facilitating the implementation of these reforms. 相似文献

This article sets out to examine the degree of persistence in the real exchange rates of Kazakhstan, Kyrgyzstan and Russia, and tests the validity of Purchasing power parity (PPP) using monthly data covering 1995:01–2013:12 period. The sum of autoregressive (AR) coefficients is used in order to examine persistence of the real exchange rate series and grid-bootstrap method is employed for the confidence intervals. The tests performed suggest two results: (1) Covering the full sample and sub-sample periods, excluding Kyrgyzstan in 1995:01–1998:07 and Russia in 2008:09–2013:12 periods, disregarding the structural breaks in the data generating process, there is high persistency in real exchange rates; (2) there is evidence in support of PPP covering the full sample for every country except for Kyrgyzstan in 1995:01–1998:07 and Russia in 2008:09–2013:12 periods. 相似文献
