This paper uses survival analysis to examine the factors determining the time taken for branches of foreign banks in Shanghai, China to make a positive rate of return after entering that market. Particular attributes of banks including the parent bank's size, early entry and the number of branches the bank has in China are found to reduce time to profitability. Market conditions in Shanghai, captured by levels of foreign direct investment and Eurodollar interest rates, are also found to have significant effects. A number of managerial implications are drawn from the analysis in light of the greater access to the Chinese banking markets following China's accession to the WTO. To ensure long‐term profitability in Shanghai, the foreign bank needs to contain costs and risks in the new markets, formulate an effective market penetration strategy, identify appropriate customer target groups, attract businesses from firms of different countries, seek early entry and undertake more fee‐income generating businesses.

Relatively little is understood about factors triggering entrepreneurial behaviour within organizations not driven by profit motives. Governance plays an important role in non‐profits, particularly boards of directors. Integrating resource‐based theory and entrepreneurial orientation research, we examine the influence of non‐profit boards as strategic resources shaping the organization's entrepreneurial orientation and performance. In particular, we focus on the non‐profit board's underlying behavioural orientations, or the extent to which the board is strategic, activist, conservative, and cohesive. Findings from a cross‐sectional survey on arts and culture organizations demonstrate that three of these behavioural orientations impact levels of entrepreneurship occurring within non‐profits. Higher levels of entrepreneurship affect social performance, but not financial performance. 相似文献

Application of the production constrained gravity-type spatial interaction model generally incorporates a “balancing of attractions” procedure to yield the fully constrained condition. Two techniques for balancing a singly constrained gravity model are compared in this note. These are the Federal Highways Administration adjusted attraction factor method and the Furness column and row balancing procedure. This comparison shows firstly that the two techniques are identical, and secondly that the balancing procedure results in an arbitrary distortion of the calibrated distribution function. Furthermore, some empirical results show that the balancing procedure does not necessarily improve the model's predictions on a cell by cell basis. These results indicate that balancing may be an unnecessary as well as undesirable step in the application of the singly constrained gravity model. 相似文献

A Cramér-type large deviation theorem for sums of functions of higher order non-overlapping spacings
Let U 1, U 2, . . . , U n–1 be an ordered sample from a Uniform [0,1] distribution. The non-overlapping uniform spacings of order s are defined as \({G_{i}^{(s)} =U_{is} -U_{(i-1)s}, i=1,2,\ldots,N^\prime, G_{N^\prime+1}^{(s)} =1-U_{N^\prime s}}\) with notation U 0 = 0, U n = 1, where \({N^\prime=\left\lfloor n/s\right\rfloor}\) is the integer part of n/s. Let \({ N=\left\lceil n/s\right\rceil}\) be the smallest integer greater than or equal to n/s, f m (u), m = 1, 2, . . . , N, be a sequence of real-valued Borel-measurable functions. In this article a Cramér type large deviation theorem for the statistic \({f_{1,n} (nG_{1}^{(s)})+\cdots+f_{N,n} (nG_{N}^{(s)} )}\) is proved. 相似文献

This article introduces the special issue on the intersection between industrial organization and healthcare economics. This intersection has received increasing research interest, growing from 2% of the industrial-organization literature in 1991 to 6% in 2016. We describe the nine included articles, which cover a range of healthcare markets that include hospital services, insurance, and pharmaceuticals. 相似文献

This paper estimates the effects of code-sharing, antitrust immunity, and Open Skies treaties on prices, output, and capacity
using an eleven-year panel of U.S.-Europe data. Code-sharing and immunized alliances are found to have significantly lower
prices than does traditional interline (multi-carrier) service, but the effects are smaller in magnitude than those found
in previous results that rely on cross-sectional data. Statistical tests that prices for immunized alliance service are equal
to online (single carrier) service often cannot be rejected, providing additional evidence that immunity grants allow immunized
carriers to internalize a double marginalization problem. Estimated output effects, consistent with the price effects, show
that alliances are associated with large increases in passenger volumes. Lastly, estimates suggest that capacity expansions
associated with “Open Skies” treaties are due entirely to expansion by immunized carriers on routes between their hubs.

The paper shows that the impact of a call-back service on the financial position of the monopolists in the countries where call-back service is offered, will in many cases be positive. The explanation for this result is found by observing cost and revenue streams, and by taking note of the various elasticities and feedback effects when ever there is an increase in traffic. For carriers selling call-back minutes to service providers, it is the proportionate return rule that provides then with a major, and perhaps the main source of profit on the call-back minutes they sell. The rule provides for the transfer of incoming IDD minutes and the associated hugely profitable settlement credits, from the other competing carriers, to the carrier selling call-back minutes. In this regard, the rule is not even-handed. The higher the market share of the carrier selling call-back minutes, the less well they do under the rule, so much so that under some circumstances a carrier selling call-back minutes at an apparent profit, would actually suffer losses on those minutes. 相似文献
