The spatial arrangement of tenants is currently one of the main topics in shopping centre research. This paper shows how a Geographic Information System (GIS) can be used to analyse the tenant structure. Given the recommendations in the literature, the analysis may help to improve the situation within a certain shopping centre. Therefore, we introduce the variable clumping method and kernel density estimation into shopping centre research in order to analyse retail category concentrations, customer flows and coupling in a shopping centre. Applying these techniques to a German shopping centre showed that spatial concentration can be observed within the retail categories of food, health & body and fashion and that the pass ratio declines according to the distance from the central point of the shopping centre. Also, shops in the same retail category have higher coupling than those of different categories, and unexpectedly spatially separated shops have a slightly higher coupling than non-spatially separated ones. Overall, the use of GIS improves the quality and the speed of spatially based analysis, and thus should be used more frequently in scientific shopping centre research and shopping centre management.  相似文献

Job creation, job destruction, and the real exchange rate   总被引:1,自引:0,他引:1  
Welfare gains from trade are reduced by adjustment costs associated with factor reallocation, but most studies of the effects of trade on labor markets focus only on net employment change. This paper takes a step toward identifying trade-related adjustment costs by estimating the effects of real exchange rates on labor reallocation using a new model of gross job creation and destruction applied to detailed U.S. manufacturing industries between 1973 and 1993. Trend real exchange rates significantly affect job reallocation but not net employment. Cyclical real exchange rates significantly affect net employment through job destruction only.  相似文献

The idea of spontaneous order is here exposited by analogy with roller skating at a roller rink. In the roller rink and in the economy, the key ingredient of spontaneous order is coincidence of interest. This makes the beneficial outcome possible. Central planning is bound to fail if for no other reason than because of the knowledge problem. The meaning of ‘spontaneous’ is discussed, along with the limits of the principle.  相似文献

We show how capital structure swaps can increase the wealth of a firm's long‐term shareholders when a firm's debt or equity is misvalued. We review the conventional rule that a firm should issue equity and use the proceeds to retire outstanding debt (an equity‐for‐debt swap) when equity is overvalued, or repurchase equity with proceeds of new debt (a debt‐for‐equity swap) when equity is undervalued. We also analyse the more complex case where a firm's debt and equity are both undervalued, showing the optimal swap may be to issue undervalued equity, contrary to the conventional rule.  相似文献

The Fisher Body–General Motors case illustrates the costs of using inherently imperfect long‐term contracts to solve potential holdup problems, and therefore the advantages of vertical integration. Fisher Body held up General Motors by renegotiating its body supply contract so that, contrary to the original understanding, General Motors made half of the required investments in new body plants. This led to a decline in Fisher Body’s capital to sales ratio and, under the unchanged cost‐plus contract terms designed to provide Fisher Body with a return on its equity capital investments, produced a substantial wealth transfer from General Motors to Fisher Body. General Motors accepted this unfavourable contract adjustment because it was operating under a long‐term exclusive dealing contract that limited its ability to negotiate with Fisher over co‐located body plants. The exclusive dealing contract designed to protect Fisher Body’s original GM‐specific capacity investments against a potential holdup by General Motors thereby created a Fisher Body holdup of General Motors. The way in which Fisher Body accomplished its holdup demonstrates the importance of distinguishing inefficient holdup threats from efficient actual holdups.  相似文献

The dynamics of exchange rate regimes: Fixes, floats, and flips   总被引:1,自引:0,他引:1  
The impermanence of fixed exchange rates has become a stylized fact in international finance. The combination of the “mirage” view that pegs do not really peg with the “fear of floating” view that floats do not really float generates the conclusion that exchange rate regimes are, in practice, unimportant for the behavior of the exchange rate. This is consistent with evidence on the irrelevance of exchange rate regimes for general macroeconomic performance. Recent studies, however, show that the exchange rate regime matters. This can be understood by considering the dynamics of exchange rate regimes. We demonstrate that the “mirage” view is somewhat misleading and incomplete. Pegs frequently break, but many do last. Also, there is a high degree of flipping, that is, the re-formation of pegs that have broken. Thus, a fixed exchange rate today is a good predictor that one will exist in the future. We also investigate the quantitative effect of fixed exchange rates. While the “fear of floating” view suggests little actual difference in fixed and floating rates with respect to exchange rate volatility, we show that fixed exchange rates exhibit considerably greater bilateral exchange rate stability than flexible rates, both today and in the future.  相似文献

We examine how country-level institutional context moderates the relationship between three socio-cognitive traits—entrepreneurial self-efficacy, alertness to new business opportunities, and fear of failure—and opportunity entrepreneurship. To do this, we blend social cognitive theory (SCT) with institutional theory to develop a multi-level model of entrepreneurial entry. We merge data from the Global Entrepreneurship Monitor (GEM) surveys and the Economic Freedom of the World (EFW) index for 45 countries from 2002 to 2012. Our results, which are based on a multi-level fixed-effects model, suggest that entrepreneurs' self-efficacy and alertness to new opportunities promote opportunity entrepreneurship while fear of failure discourages it. However, the strength of these relationships depends on the institutional context, with entrepreneurial self-efficacy and alertness substantially more likely to lead to new opportunity-driven ventures in countries with higher levels of economic freedom. These results provide suggestive evidence that economic freedom not only channels individual effort to productive entrepreneurial activities, but also affects the extent to which individuals' socio-cognitive resources are likely to mobilized and lead to high-growth entrepreneurship.  相似文献
