Of all the nations that inhabit the three largest parts of the globe, the Japanese deserve to rank the first, and to be compared with the Europeans—C. P. T hukberg [ Travels , 1796, vol. Ill, p. vi. 相似文献

This paper deals with the problem of determining the optimum combination of sheep and beef cattle on grazing properties. A major difficulty is that iso-cost functions (production possibility curves) for sheep and cattle are unstable and difficult to estimate because of sheep-cattle-pasture interaction. After discussion of theoretical difficulties consideration is given to practical approaches, based on the iso-cost function concept, which might provide graziers with useful guide-lines. Evidence is presented which suggests that the substitution rate between sheep and cattle with respect to pasture is not constant, and probably varies with stocking rate. 相似文献

Closed-form solutions are derived and interpreted for European options, with stochastic strike prices, that maintain constant
elasticity of the strike with respect to the price of the underlying asset. We refer to such options as CUES. CUES preserve the relative shares of exercise price risk for both the buyer and writer of the option, regardless of whether
the price of the underlying asset moves up or down. The relevance of the CUES concept is established through applications
in two distinct fields. First, it is established that CUES-like options are embedded in private equity investments. This concept
is then used in a novel application to determine the equity share of a private company corresponding to a given level of investment.
Secondly, the advantages that CUES would provide over traditional executive stock option grants are considered and it is shown
that CUES can provide enhanced incentive-alignment without increasing options expense to the company.

Recent contributions to the literature have resulted in a standard modelling of office markets. The models provide considerable insight into the working of office markets. • Nonetheless, a major difficulty is the use of data for a single city or aggregate data for the U.S. The latter implicitly assumes that model structure is invariant across cities. In this article we test for structural differences in office markets by size class. Rental data from REIS Reports for twenty-one metropolitan areas for the time period 1981 to 1990 are used to model office market behavior. Results suggest market outcomes vary by city size, larger markets are better modelled using standard procedures, and Manhattan behaves quite differently from the other markets. 相似文献

Empirical research about tax evasion and the informal economy has exploded in the past few decades, seeking to shed light
on the magnitude and (especially policy) determinants of these phenomena. Quantitative information informs the analysis of
policy choices, enables the testing of hypotheses about determinants of this phenomenon, and can help with the accurate construction
of national income accounts. Even as empirical analysis has burgeoned, some have expressed doubts about the quality and usefulness
of some prominent measures. The fact that high-quality data is elusive is neither surprising nor a coincidence. The defining
characteristic of tax evasion and informal economic activity—that they are generally illegal—often renders unreliable standard
data collection methods such as surveys. Unlike invisible phenomena in the natural sciences, these invisible social science
phenomena are hard to measure because of choices made by individuals. Analysis of tax evasion and the informal economy must
proceed even in the absence of the direct observability of key variables, and theory should guide the construction and interpretation
of evidence of the “invisible.” In this paper, we address what can be learned using micro or macro data regarding tax evasion
and the informal economy under given conditions and assumptions, and critically review some of the most common empirical methods
in light of our conclusions. We conclude with an entreaty for researchers in this field to enlist in the “credibility revolution”
(Angrist and Pischke in J. Econ. Perspect. 4(2):3–30, 2010) in applied econometrics. 相似文献

Mackay Whitsunday Safe Communities (MWSC) was developed using a capacity building model that consciously attempted to design sustainability into the network. Our aim was to quantify the flow of resources used by MWSC to implement and sustain its injury control activities. Resource exchange among network members was quantified and analysed using social network analysis. In 2004, MWSC accessed an estimated 6.5 full-time staff equivalents and $0.9 million. However, these resources were largely accessed externally. The linking relationships that connected MWSC to its external support network, more than half of which were maintained by six broker network facilitators, were the critical social asset used to access resources and sustain network productivity. The sustainability of this network and arguably similar safety promotion networks is vulnerable to the changing priorities of external sponsoring agents and highly dependent on its leaders who facilitated access to the resources it required to remain productive. 相似文献

This article explores how Human Resource (HR) policies and practices influence employee perceptions of organizational justice, which in turn impacts employee emotions and feelings of emotional exhaustion. Using structural equation modelling and based on employee survey data drawn from two manufacturing organizations, we find that a strong HR system — perceived by workers as distinctive, attractive and consistently implemented — fosters perceptions of distributive, procedural and interactive justice. However, only distributive injustice leads to negative emotions and emotional exhaustion. This is explained by reference to the cultural and institutional context (China), status (migrant) and type of workers (semi‐skilled, manual) included in the study. We discuss the theoretical and practical implications that arise from these findings. 相似文献

Using credit reporting firm records on 7 million individuals in the United States, we first demonstrate that debt in collections varies significantly across the country; specifically, the South and West regions have higher shares of individuals with debt in collections than other regions. Second, we identify local factors that are strongly related to debt in collections. Results from our regression models show that neighborhoods with higher rates of debt in collections are more likely to have (1) lower health insurance coverage; (2) lower home values and homeownership rates, (3) a higher share of delinquent and underwater mortgages, (4) lower household incomes, and (5) a higher share of African Americans and Latinos. While our analysis does not identify the causal mechanisms that determine financial distress, the analyses developed here can facilitate research on such mechanisms. 相似文献
