在对新创企业的成长阶段进行划分的基础上,采取典型案例研究方法,分阶段地探讨高管行为整合与新创企业成长阶段的匹配性。研究发现:新创企业的成长在青春期阶段与高管行为整合的关系为不匹配,在调整期阶段与高管行为整合的关系需要根据企业是否具有行为整合的条件来确定,在稳定期阶段与高管行为整合的关系为匹配。 相似文献

We extend the standard textbook search and matching model by introducing deep habits in consumption. This assumption generates amplification in the response of labour market variables to technology shocks by producing endogenous countercyclical mark-ups. The cyclical fluctuations of vacancies and unemployment in our model can replicate those observed in the US data, with labour market tightness being 20 times more volatile than consumption. Vacancies display a hump-shaped response to technology shocks and the numerical simulations generate an artificial Beveridge curve that is in line with the data. Our model preserves the assumption of fully flexible wages for new hires and the calibration is consistent with the estimated elasticity of unemployment to unemployment benefits. Finally, we show that in contrast to models with exogenous mark-up shocks, the deep habits model does not require an implausible variation in the elasticity of demand to match the volatility of labour market variables, and the cyclical properties of the mark-up are in line with empirical evidence. 相似文献

This paper investigates a Western retailer's market orientation levels in two emerging markets. We examine whether the market orientation-company performance link holds true for retailers in emerging economies, despite environmental differences. By using concepts from key studies we have assimilated a fully representative model - applied through interviews with top management from Tesco and its subsidiaries and affiliates in Hungary and Slovenia. Using this example, we find that the market orientation-business performance link is valid for Western retailers in emerging economies. Here, the retailer applied market orientation predominately through; the use of matching with suppliers of own brand goods; top management emphasis on market orientation and risk taking. Intelligence generation and dissemination was exercised via global processes such as brand review. 相似文献

The paper studies the effects of fiscal expansion on the Japanese labor market. First, using a structural VAR model, we find that the unemployment rate falls and employment rises following an increase in government spending. We also find that fiscal expansion affects flows in and out of unemployment. While an increase in government spending increases the job-finding rate, it reduces the separation rate. We then incorporate search and matching frictions into a standard dynamic general equilibrium model, and study whether the model can explain what we observed in data. While the model fails to predict the exact size of the impact of government spending shocks on the Japanese labor market variables, it can consistently capture the empirical pattern of responses of labor market variables to shocks. 相似文献

This paper examines the effects of fiscal stimuli in the form of job creation subsidies in a DSGE model with search friction and endogenous job separation. We consider two types of job creation subsidies: a subsidy for the cost of posting vacancies and a hiring subsidy. This paper finds that the effects of job creation subsides on unemployment differ between models with and without endogenous job separation. While a positive job creation subsidy shock lowers unemployment in a model without endogenous job separation, it increases unemployment in a model with endogenous job separation. We also find that while qualitatively the effects of a vacancy cost subsidy on the economy are similar to those of a hiring subsidy, quantitatively they are different. 相似文献

We aim to compare the activities of the two main credit guarantee institutions in Korea. There has been mounting criticism that although these institutions were mandated to play different roles in financing small and medium‐sized enterprises (SME), their operations are, in fact, similar, and many SME receive overlapping support from both institutions. Using the propensity score matching method (allowing for multiple, mutually exclusive support scenarios) to compare the effects of PCG on different institutions, the present study provides suggestions to help the government make decisions regarding the consolidation of PCG funds. The results suggest that the institutions function differently and target different SME. However, overlapping support enables firms to expand their sales only, indicating the existence of inefficiency in the case of overlapping support to firms. 相似文献

Maize is the most important food staple in Eastern and Southern Africa, with a highly seasonal production but relatively constant consumption over the year. Farmers have to store maize to bridge seasons, for food security and to protect against price fluctuations. However, the traditional storage methods do not protect grain well, resulting in large postharvest losses. Hermetically sealed metal silos kill storage pests by oxygen deprivation without pesticides. Popular in Central America, they are now being promoted in Africa, but their impact here has not yet been studied. This study used propensity score matching to evaluate the impact of metal silos on duration of maize storage, loss abatement, cost of storage, and household food security. Metal silo adopters (N = 116) were matched with non-adopting farmers from a representative sample of 1340 households covering the major maize-growing zones in Kenya. The major effect of the metal silos was an almost complete elimination of losses due to insect pests, saving farmers an average of 150–200 kg of grain, worth KSh9750 (US$130). Metal silo adopters also spent about KSh340 less on storage insecticides. Adopters were able to store their maize for 1.8–2.4 months longer, and to sell their surplus after five months at good prices, instead of having to sell right after the harvest. The period of inadequate food provision among adopters was reduced by more than one month. We conclude that metal silos are effective in reducing grain losses due to maize-storage insects, and that they have a large impact on the welfare and food security of farm households. The initial cost of metal silos is high (KSh20,000/1.8 ton) and therefore policies to increase access to credit, to reduce the cost of sheet metal, and to promote collective action can improve their uptake by smallholder farmers. 相似文献

菜肴烹制成功以后即要进行装盆、美化。但由于菜肴有着各种各样的色泽、形态,而用来盛装的器皿也是多种多样,不一而足,故如果不注意美食与美器的搭配艺术,则势必影响到菜肴美化的总体效果。所以,文章从美食与美器如何谐合的角度与同行来进行探讨、商榷。 相似文献
