This paper analyzes the optimal adjustment strategy of an inventory‐holding firm facing price‐ and quantity‐adjustment costs in an inflationary environment. The model nests both the original menu‐cost model that allows production to be costlessly adjusted, and the later model that includes price‐ and quantity‐adjustment costs, but rules out inventory holdings. It is shown that the firm's optimal adjustment strategy may involve stockouts. At low inflation rates, output is inversely related to the inflation rate, and the length of time demand is satisfied increases with the demand elasticity but decreases with the storage cost and the real interest rate. 相似文献

In recent years a growing stream of research has examined the relationships between structural characteristics of regions and their levels of new firm formation. This empirical study aims at supplementing such findings with analyses that include other forms of business dynamics, and also the possible well-being effects of such dynamics. From a unique and comprehensive data set that tracks all births, deaths, expansions, and contractions of commercial business establishments in Sweden 1985–89, six groups of regions with different patterns of dynamics are extracted by means of cluster analysis. The clusters' structural characteristics and their development of economic well-being are also compared. The results suggesta) that the patterns of business dynamics are contingent on the structural characteristics of regions,b) that high formation and turnover of establishments are associated with a relative increase in economic well-being, andc) that small, autonomous firms have a vital role in this process. 相似文献

In this paper, we explicitly introduce regional factors into a global dynamic factor model. We combine new open economy factor models (emphasizing global shocks) with the recent findings of regional importance in the business cycle synchronization literature. The analysis is applied to a large panel of domestic data for four small open economies. We find that global and regional shocks explain roughly 30 and 20 percent, respectively, of the business cycle variation in all countries. While global shocks have most impact on trade variables, regional shocks explain a relatively large share of the variation in cost variables. 相似文献

This paper studies the assignment of decision makers to two committees that make decisions by a simple majority rule. There is an even number of decision makers at each of the various skill levels and each committee has an odd number of members. Surprisingly, even with the symmetric assumptions in the spirit of Condorcet, a symmetric composition of committees is not always optimal. In other words, decision makers with different skill levels should not generally be evenly divided among the committees. However, in the special case of only two skill levels, it is optimal to compose the committees evenly. 相似文献

In this paper, we demonstrate that many stochastic volatility models have the undesirable property that moments of order higher
than 1 can become infinite in finite time. As arbitrage-free price computation for a number of important fixed income products
involves forming expectations of functions with super-linear growth, such lack of moment stability is of significant practical
importance. For instance, we demonstrate that reasonably parametrized models can produce infinite prices for Eurodollar futures
and for swaps with floating legs paying either Libor-in-arrears or a constant maturity swap rate. We systematically examine
the moment explosion property across a spectrum of stochastic volatility models. We show that lognormal and displaced-diffusion
type models are easily prone to moment explosions, whereas CEV-type models (including the so-called SABR model) are not. Related
properties such as the failure of the martingale property are also considered.

Sources of risk in contemporary tourism vary over a long array of phenomena ranging from the risk of terror attacks to risks related to food and consumption. Currently, alleged food-risk sources such as Creutzfeldt–Jacobs Disease (CJD; commonly known as “Mad Cow Disease”), Salmonella, Scrapie disease and even genetically modified food are salient in mass media.In the present study, we addressed the pervasiveness of tourists’ judgements of such food-related risks. As part of a larger study, some 1880 individual tourists (from 48 different nations) answered a questionnaire pertaining to food-risk issues. Based on the logics of the availability heuristic, we expected that food risks would be judged to be lower in one's own home country than abroad. We also expected that people would rate various sources for food risk differently when rating food risks at home and abroad.The results indicate that risks linked to food are indeed perceived to be higher abroad than at home, regardless of where the respondents’ homes are, although attributions of risk to the various risk sources seem to vary between at home and abroad. The results also show a significant, but moderate correlation between travel experience and food-risk judgements abroad and at home. The results also indicate cultural differences in risk judgements concerning food. 相似文献

Organisations frequently follow brand extension strategies. This paper investigates the impact of category similarity, brand reputation, perceived risk and consumer innovativeness on the success of brand extensions in FMCG, durable goods and services sectors. A set of hypotheses were developed and tested in a study amongst 701 consumers. The findings show that extensions into categories more similar to the original brand tend to be more readily accepted. Likewise, the reputation of the original brand is an important factor influencing the success of the extension. These findings are consistent across FMCG, durable goods and services brands. However, perceived risk about the extension category was only found to enhance acceptability of extensions for durable goods and services brands. Innovative consumers are more positively disposed towards service brand extensions than FMCG and durable goods brand extensions. 相似文献
