We assess the importance of downward nominal wage rigidity (DNWR) in Canada using employer‐level administrative data from the major wage settlements (MWS) and household‐based survey data from the Survey of Labour Income Dynamics (SLID). MWS data cover large unionized firms in Canada, while SLID is a rich rotating panel representative of the employed population in Canada. Combining both sources of information allows for an extensive analysis of DNWR in the Canadian labour market. We find large shares of wage freezes and smaller shares of wage cuts in both MWS and SLID. Shares of freezes are higher at lower CPI inflation rates, based on provincial data. These observations are consistent with the presence of DNWR. DNWR in Canada appears to be larger than in other countries such as the United States, the United Kingdom and European countries. The incidence of DNWR is heterogeneous across firms’ and workers’ characteristics. Wages report less DNWR over longer horizons.  相似文献

In this paper, we derive the optimal investment policy in a high-speed rail transport (HSR) project. We assume that the source of uncertainty comes from the annual demand, and that it follows a geometric Brownian motion with jumps of random magnitude, occurring in random times, according to a Poisson process. We assess the impact of these shocks on the demand threshold, along with the investment opportunity value and option to differ. We consider several distributions for these jumps, and we compare with the no-jumps case. Numerical results are presented, showing the importance of assumptions about the underlying stochastic process.  相似文献

With over 50 million Hispanics living in the United States commanding 1.2 trillion dollars in purchasing power, Hispanic wine consumers may comprise a lucrative market for the saturated wine industry. Yet the wine industry has largely ignored consumers who do not fit the profile of its traditional demographic base. This study aims to fill a gap in the existing body of knowledge on Hispanic consumers of wine. Building on acculturation theory, the current study investigates predominant attitudes, opinions, and interests of the Hispanic consumer relating to wine consumption. The results of three focus groups indicate that the core cultural values of family, food, and social interaction are critical factors in developing an interest in wine among Hispanic wine consumers. Levels of acculturation also play a significant role in wine consumption among Hispanic consumers. Special attention should be addressed to younger, more acculturated consumers, as they are not only the primary consumers of wine but also advocates for wine for their parents and other groups of consumers.  相似文献

This article analyses the determinants associated with the use of the Integrated Report (IR) as a corporate reporting model for sustainability information. IRs provide information regarding the use and interdependence of different company resources. The previous literature has identified determinants behind the presentation of IRs at the country level (legal system, investor protection, economic development, cultural characteristics) as well as at the company level (size, industry, verification of the sustainability report). Our work contributes to the literature by using a novel statistical approach that addresses the likelihood of the non‐independence of data: companies in the same country are more similar to one another than are companies from different countries. Our results confirm significant inter‐country variance, which may be partially explained by the existence of specific regulations and the individualism vs. collectivism dimension. Although we confirm the effect of company‐level determinants, our results do not support the role of specific variables tested as determinants.  相似文献

Much of the work on real options assumes that the underlying state variable follows a geometric Brownian motion with constant volatility. This paper uses a more general assumption for the state variable process that better captures the empirical regularities found in commodity markets. We use the constant elasticity of variance diffusion, where volatility is a function of underlying asset prices, and we provide analytic solutions for perpetual American options. We show that a firm that uses the standard lognormal assumption is exposed to significant errors of analysis, which may lead to nonoptimal investment and disinvestment decisions. © 2010 Wiley Periodicals, Inc.

Over the last few decades, especially in urban areas, there has been a revival of the notion of quality of life in connection with periurban green spaces, the presence of which is thought to improve emotional well-being. This paper aims to determine how far the monetary valuation of this environmental resource is influenced by aspects relating to users’ emotional experience and satisfaction. The contingent valuation method is used to estimate monetary valuation and structural equation models allow examination of the relationships between visitor attitude and behaviour variables. The study focuses on two periurban green spaces in Spain and the data are obtained by means of face-to-face, in situ surveys of visitors. The findings support the relationship between visitor attitudes and the monetary valuation of this environmental good, revealing the need to advance further in exploring the potential of such natural resources to enhance urban social well-being.  相似文献

This study examines the economic impact of sustainable agricultural production systems in Central America. In particular, we investigate the impact of investments promoted by the MARENA Programme in Honduras on the total value of agricultural production (TVAP) of its beneficiaries. Propensity Score Matching techniques along with the Difference‐in‐Differences framework are used to mitigate biases stemming from differences in observed as well as unobserved (time‐invariant) characteristics between beneficiaries and a control group. The econometric estimates suggest that MARENA has had a positive and significant effect on the TVAP of beneficiaries. In addition, the analysis shows that, under alternative scenarios, MARENA yielded higher than expected internal rates of return. The results of this study shed light on the response of small‐scale hillside farmers to economic incentives and lend support to the role of natural resource management projects in Central America as a tool to increase household income while also promoting the conservation of natural resources.  相似文献
