The effects of oil price shocks on job reallocation

We investigate the effect of oil price innovations on U.S. manufacturing job flows using a simultaneous equation model that nests symmetric and asymmetric responses. We find no evidence of asymmetry in the response of job flows to positive and negative oil price innovations. We then inquire whether firms, when facing positive shocks, shed jobs faster than they create jobs. We show that positive innovations lead to a decline in net employment and an increase in job reallocation, possibly due to search and matching issues. Yet, the latter effect becomes statistically insignificant when we control for data mining. We demonstrate that the cumulative one-year effect of oil price shocks on job creation and destruction was smaller during the Great Moderation, but it was larger for gross job reallocation. These variations were caused by a change in the transmission channel and not by smaller oil price shocks.     

Exchange rate and foreign price effects on UK inflation

The issue of incomplete pass-through from exchange rate changes to domestic inflation has received considerable attention. Most models try to account for this by using a variety of assumptions about the costs of changing prices. These suggest complete pass-through, but only after the possible elapse of a considerable delay. In contrast, in this article Graeme Chamberlin and Brian Henry provide evidence that exchange rate effects on inflation may be non-linear and, more specifically, subject to thresholds. Their tentative results suggest this may be important in describing price-setting behaviour in the UK.     

Consumption and price effects of state-run liquor monopolies

Uniform pricing policies practiced by state monopoly liquor systems are not consistent with a stated objective of revenue-maximization from liquor sales. If some residents in a monopoly state buy alcoholic beverages in neighboring, lower-priced states, the monopoly state could increase revenues by lowering prices in the appropriate border counties. The empirical analysis looks at Ohio and finds that residents tend to purchase fewer and less expensive bottles of liquor in state-run stores which border states with lower liquor prices. The result is several million dollars a year of lost revenue to Ohio.     

Factors affecting variations in health services utilization in Quebec, Canada.

This study investigates the changing patterns of health services utilization in sixty-four (64) medical market areas and the factors that affect such changes. The relationship of area and personal characteristics to variations in use of health services in these areas were examined by multivariate analysis of data obtained from Regie de L'assurance-maladie du Quebec (Bureau of Insurance in Quebec) and Statistics Canada. Analyses of the data revealed that disparities in use exist between low and high income areas. The impact on health services utilization of the Universal Medical Care Insurance in Quebec was studied. Findings of the study have implications for NHI in the United States.     

房价与地价，谁拉动了谁？

持续上涨的房价成为社会关注的民生话题，也是政府宏观调控的重要切入点。有些人认为，房价居高不下，是由于实行招拍挂后地价太高，是地价高导致了房价高。只要降低地价，就可以把房价降下来。现实情况是不是这样，很值得商榷。     

The role of aggregation in estimating the effects of private school competition on student achievement

This paper investigates possible reasons for the disparity in results in the private school competition literature. In particular, the focus is on the data set, the grade range, and level of aggregation of the competition variable, and on the choice of OLS or IV estimation strategies. The results show that the size and significance of the competition variable depends on each of these attributes, although the grade range of the competition variable has a slightly smaller impact than the others. Private school competition does not have a consistently positive, significant effect on student achievement.     

Markov models and the utilization of mental health services: a study of endogenously depressed patients.

Patients in the mental health care system typically make more or less irregularly spaced visits to psychiatrists, both within and between episodes of a given illness. A Markov model is constructed which can predict the utilization of psychiatric services for such patients. Unlike previous Markov models of utilization, the current model takes as its starting point a model of an actual disease, specifically, endogenous depression. It is shown how one can estimate the parameters of both the model of utilization and the model of depression using data which were collected for clinical research purposes. The models provide reasonable fits to the data. Several applications of the models are worked out. In addition to predicting the utilization of mental health services, the models can be used to predict incidence, prevalence and recovery rates and to predict the changes in utilization which parallel changes in treatment regimens.     

破解土地价格“剪刀差“难题——以重点城市的居住地价和工业地价为例

“剪刀差”概念源于20世纪20年代前苏联的超额税，是对不合理的工农业产品价格的概括，其实质是工农业产品的不等价交换。随着我国城市化和工业化的不断推进，地价“剪刀差”这一现象开始在我国土地市场领域中出现，而且这种差异呈现不断拉大的趋势。然而，学者们较多关注的是政府廉价征地和高价出让土地之间的地价“剪刀差”现象，对不同用途土地价格的‘剪刀差”现象研究得很少。因此，对近几年我国重点城市的居住地价和工业地价的“剪刀差”现象进行一些研究，分析不同用途土地价格‘剪刀差”存在的原因并提出解决方法，很有必要。

Modelling the use of health services by populations of small areas to inform the allocation of central resources to larger regions.

Modelling the use of health services by local populations can inform the allocation of central resources to larger regions. At aggregate, e.g. regional, level, use is largely driven by supply and such analysis can be misleading. At small area level, however, populations effectively compete for services and their different relative use of services, after allowing for varying availability, reflects variations in their relative need. Empirical quantitative estimates can thus be made of the net relation of factors such as mortality or social deprivation to relative need for health services. These estimates can then be used in weighted capitation formulae for allocating resources to larger regions.     

Modelling short- and long-term effects in the aggregate demand for soft drinks

A dynamic regression model for non-durable commodity demand is specified based on the additive unobserved components seasonal model with causal variables. The seasonal component which includes retailer stock effects is modelled as a seasonal ARMA process with fixed temperature effects. The non-seasonal component incorporates both short-run consumer responses and long-run adaptation to steady-state growth paths. Aggregation effects on per capita demand caused by the increase of new consumers as real income grows are investigated and the resulting growth trends accounted for. It is shown that neglecting these trends in the long-run adaptation process is likely to produce biased predictions and misleading estimates of crucial response parameters.

Threshold Modelling of Stock Return Volatility on Eastern European Markets.

A common finding for developed stock markets is that negative shocks entering the market lead to a larger return volatility than positive shocks of a similar magnitude. The following paper considers two emerging Eastern European Markets where the first point of investigation is whether an analogous asymmetric characteristic is reflected in emerging markets. The second point of investigation is whether the findings differ depending on the institutional microstructure of the exchange being examined. Hence, econometric techniques are adjusted and a ‘double-censored tobit GARCH’ model is developed. This paper finds that no asymmetry exists on either markets and possible reasons for this are proposed. JEL Classification: G14, G15, P21, P34. This revised version was published online in July 2006 with corrections to the Cover Date.     

The price of success: balancing the effects of entrepreneurial commitment,work-family conflict and emotional exhaustion on job satisfaction

This research explores job satisfaction among entrepreneurs to investigate two paths from entrepreneurial commitment to job satisfaction: the direct path and the family path that includes work-family conflict and emotional exhaustion. An empirical study of 232 small and micro firm business owners are used to test the hypotheses seeking to understand which path to job satisfaction has the greatest influence. The results indicate that although being committed to one’s own business increases job satisfaction, emotional exhaustion takes a greater toll. We conclude that negative aspects of entrepreneurship exert an important influence on entrepreneurs’ satisfaction with their job. These findings offer important theoretical and practical implications.
