The stock of mobile telephones has surpassed fixed phones in Korea. Presently, the density is more than 60 of every 100 inhabitants. Thus, the potential for mobile telephones to become a substitute for, and directly compete with fixed telephones, has become evident. The aim of this paper is to examine the impact of rapid growth in mobile telephones on the access demand for traditional fixed telephones. The study shows that a 1% increase in the number of mobile telephones results in a reduction of 0.10–0.18% in new fixed connections and a 0.14–0.22% increase in fixed disconnections. The empirical analysis is carried out with Korean regional panel data for the period 1991–1998. The study is relevant to several important public policy issues. 相似文献

利用1996年～2007年全国27个省、直辖市、自治区的面板数据模型,考察了最低工资标准对就业的影响。实证结果表明,最低工资标准的提高对全国总体就业有负影响,但影响力度很小。进一步的地区分析表明,最低工资标准的提高对东、西部地区的就业有负影响,对中部地区的就业则无显著性影响。最后给出了相关的政策建议。 相似文献

An empirical analysis of inventory turnover behaviour in Greek retail sector: 2000-2005 总被引：1，自引：0，他引：1

In this study we investigate the determinants of inventory turnover. The study is based on an econometric analysis of inventory behaviour using an inventory turnover model. The empirical implementation of the model was conducted on a sample of financial data for 566 Greek retail firms for the period 2000-2005. By employing panel data techniques it was found that inventory turnover ratio is negatively correlated with gross margin and positively correlated with capital intensity and a measure of sales surprise.Decomposing the variance into its components associated with year, firm and retail segment effects, we found that a substantial amount of inventory turns variability is due to segment-wise effects. Moreover, the inventory turnover reaction to different sales changes was also studied. It was estimated that changes in sales bring on bigger changes when firms operate in sales-declined region. These results are useful in identifying methods and applications to improve inventory performance among firms and over time. 相似文献

Consumer reactions to food scandals and their resulting economic implication are well documented. However, studies have typically neglected the roles that consumption habits and media usage behaviours may play in explaining household’s response to food safety incidences. In this study we develop a model of heterogeneous media usage intensity, information impacts and decay over time to estimate household’s behavioural responses to the 2011 German Dioxin scandal. We are specifically interested in determining the degree of heterogeneity in household’s short-term adjustments demand patterns versus persisting long-term consumption habits of meat products (chicken and pork) directly affected by the incident. The empirical analysis employs detailed household-level retail scanner and media usage data collected by the GfK Consumer Scan panel for a total of 16,023 households over a period of 104 calendar weeks. Results of dynamic correlated random effect Tobit models indicate an important role of unobserved heterogeneity in explaining household responses during the food scandal. We find strong empirical evidence supporting our hypothesis that short-term marginal adjustments in demand and propensity to buy affected products triggered by the negative impact of household media exposure were over-compensated by habit persistence. The question of how consumption patterns evolve over time in the presence of food scandals is expected to be of interest for both policy makers and the food industry. The potential biases in the projection of economic impacts resulting from simplifying assumptions of household’s response patterns to a proliferating numbers of food safety incidences has implications for risk management and public policy. 相似文献

This paper investigates the relationship between EU agricultural subsidies and the outflow of labor from agriculture. We use more representative subsidy indicators and a wider coverage (panel data from 210 EU regions over the period 2004-2014) than has been used before. The data allow to better correct for sample selection bias than previous empirical studies. We find that, on average, CAP subsidies reduce the outflow of labor from agriculture, but the effect is almost entirely due to decoupled Pillar I payments. Coupled Pillar I payments have no impact on reducing labor outflow from agriculture, i.e. on preserving jobs in agriculture. The impact of Pillar II is mixed. Our estimates predict that an increase of 10 percent of the CAP budget would prevent an extra 16,000 people from leaving the EU agriculture sector each year. A 10 percent decoupling would save 13,000 agricultural jobs each year. However, the budgetary costs are large. The estimated cost is more than € 300,000 per year (or more than € 25,000 per month) per job saved in agriculture. 相似文献
