A time‐series approach to the determination of savings rates

Time series analysis is used to study the savings rate and its determinants. The real effective exchange rate is introduced as a new independent variable in the savings function. Borrowing constraints, the current account balance, real rate of interest, macroeconomic stability, and age dependency are shown to be significant determinants of the savings rate. In addition, the real effective exchange rate is found to be significant across countries. Violations of Purchasing Power Parity are shown to explain some of the differences in savings rates between Canada, Japan, the United Kingdom and the United States.     

Experiential Marketing and Long-Term Sales

This study investigates the ability of winery tasting rooms to create brand awareness and build long-term brand loyalty. Specifically, we test the conjecture that if tasting rooms create brand awareness and a pleasurable tasting room experience, then those visitors are more likely to recognize and seek out those brands once they leave the tasting room. To measure these effects, we exploit differences in tasting room characteristics to conduct a series of natural experiments from which we analyze differences in off-premise retail sales away from the tasting room. We use scan data on wine sold off-premise through traditional retail outlets to then test for differences among tasting room characteristics. Our results indicate that tasting rooms act as a form of experiential marketing for wineries, creating brand awareness and generating greater growth in off-premise retail sales. Finally, we address issues of endogeneity and unobserved heterogeneity as potential sources of bias.

Forecasting in Short-Term Planning and Management for a Casino Buffet Restaurant

SUMMARY

Demand fluctuation accounts for an important consideration in a restaurant's daily operational decisions. Good short-term planning and management require accurate forecasts of daily demand. The objective of this study is three-fold: (1) to apply, evaluate, and compare different methods of forecasting customer counts for an on-premises buffet restaurant of a local casino in Las Vegas, (2) to describe and propose a combined forecasting approach for this casino buffet restaurant, and (3) to explore the concept of revenue and capacity management for this buffet restaurant. Eight forecasting models were tested and evaluated by two common error measures. The results suggest that a double moving average model was the most accurate model with the smallest MAPE and RMSPE. Extensive discussions on forecasting and planning/management in buffet operations are provided along with recommended future research.

河南省地区经济差距的历史分析

改革开放近30年来,河南省各地区居民的收入水平普遍得到较大幅度的提高,但各地区之间的经济发展差距却在逐步拉大。一方面,郑州、焦作等依托省会城市或者资源优势经济得到较快发展;另一方面,信阳、驻马店等革命老区或者传统平原农业区经济增速缓慢。日益扩大的地区经济差距显然会影响资源配置效率及长期经济增长的质量,对整个河南经济发展的的可持续性带来不利影响,甚至会影响社会的安定团结。因此对河南省地区差距的度量研究显得尤为必要,但这方面的实证研究往往停留在简单的数据列举上,缺乏全面性和深入的定量分析。笔者试图以近几年河南省统计局发布的年鉴数据为基础,对河南省的地区差距作出较为全面的测度。
