Directional Land Value Gradients

The standard urban model supports the concept of a constant land price gradient throughout the urban area. It is a reasonable conjecture that the land price gradient would vary with direction from the CBD. The variation in the gradient could be caused by a number of factors, but the idea that the land price gradient is flatter along radial transportation routes than in other directions is widely recognized even though there is little rigorous empirical work supporting this belief. This paper will examine the structure of urban land prices with a focus on the land price gradient as a function of the direction around the center of the city using a piecewise linear function. The added flexibility in the gradient estimate gained by this approach reveals a dramatically varying directional land price gradient.

Buyer perceptions of supply disruption risk: A behavioral view and empirical assessment

As supply chains become more complex, firms face increasing risks of supply disruptions. The process through which buyers make decisions in the face of these risks, however, has not been explored. Despite research highlighting the importance of behavioral approaches to risk, there is limited research that applies these views of risk in the supply chain literature. This paper addresses this gap by drawing on behavioral risk theory to investigate the causal relationships amongst situation, representations of risk, and decision-making within the purchasing domain. We operationalize and explore the relationship between three representations of supply disruption risk: magnitude of supply disruption, probability of supply disruption, and overall supply disruption risk. Additionally, we draw on exchange theories to identify product and market factors that impact buyers’ perceptions of the probability and magnitude of supply disruption. Finally, we look at how representations of risk affect the decision to seek alternative sources of supply. We test our model using data collected from 223 purchasing managers and buyers of direct materials. Our results show that both the probability and the magnitude of supply disruption are important to buyers’ overall perceptions of supply disruption risk. We also find that product and market situational factors impact perceptions of risk, but they are best understood through their impact on perceptions of probability and magnitude. Finally, we find that decisions are based on assessments of overall risk. These findings provide insight into the decision-making process and show that all three representations of risk are necessary for fully understanding risky decision-making with respect to supply disruptions.     

Macroeconomic shocks and stock market returns: the case of Korea

This study examines the effects of macroeconomic shocks on key macro variables, including stock market returns in Korea, using the structural vector autoregression (SVAR) model. We suggest a three-variable SVAR model incorporating inflation, output growth and stock returns. We adopt a nonzero z-ratio restriction for the long-run identifying assumption to allow for economically meaningful relationships among variables. While our results support the negative (positive) relation of demand (supply) shocks to stock returns, we also find that demand shocks influence stock market variance more significantly than supply shocks do. The sub-period analysis finds that global market fluctuations during the global financial crisis have relatively little effect on Korean stock market performance. We also examine a generalized five-variable model that includes the foreign exchange rate and interest rate, confirming the results from the three-variable case.     

Duopoly models with a joint capacity constraint

The paper proposes a two-stage mixed duopoly model of exhaustible resource market where at the first stage the government decides on the degree of privatization of public firm and at the second stage the public and private firms decide simultaneously on the two-period extraction paths. It is demonstrated that if the two firms have symmetric technologies with increasing marginal extraction costs and the same resource stocks, then neither full nationalization of any of the two firms nor full privatization will be socially desirable. It is shown that the presence of a semi-public firm improves intertemporal allocation of the fixed resource stock. Thus, partial privatization is optimal even under exogenously fixed total outputs of each firm. For asymmetric cost case, when the public firm is less efficient than the private firm, we derive the conditions under which full nationalization or full privatization is optimal.     

DOES THE MISSION OF PROVIDERS MATTER ON A QUASI‐MARKET? THE CASE OF THE BELGIAN ‘SERVICE VOUCHER’ SCHEME

ABSTRACT 1 : In 2001, the Belgian government introduced a ‘service voucher’ scheme in the field of domestic (housework) services, following a quasi‐market mechanism which fosters competition between providers of different types as regards sector (for‐profit, public, third sector) and mission (seeking profits, home care provision to vulnerable groups and work integration of the unemployed). Empirical evidence suggests that third sector organizations focusing on a social mission recognized by a tutelary regulation are the best performing with regards to the quality of jobs and service organization, leading to a better ‘triangulation’ of the service relationship. On the other hand, for‐profit providers, especially temporary work agencies, seem to favour their capacity of adaptation to the desiderata of their clients and costs’ minimization to the detriment of the quality of jobs which are made as flexible as possible.     

TOURISM AND HOTEL COMPETITIVENESS RESEARCH

Competitiveness has been a subject of study in the manufacturing and related sectors since the early 1990s. However, only recently have some researchers started to examine the tourism and hospitality competitiveness, both conceptually and empirically, with a particular focus on tourism destinations and the hotel industry. The goal of this article is to review the published studies on destination and hotel competitiveness, provide critiques, and point out future directions in tourism and hotel competitiveness research. Such a review shall provide researchers with a good understanding of the current status of competitiveness research and with a vision for advancing the existing knowledge of destination and hotel competitiveness.     

A Critical Investigation of the Bargaining Behavior of Tourists: The Case of Hong Kong Open-Air Markets

Shopping has long been recognized as an indispensable tourist activity. Hong Kong's open-air markets, where a multitude of bargaining activities can be observed, ranked as the second most popular of the island territory's diverse range of attractions in 2008 in terms of tourist arrivals. To develop cutting-edge marketing strategies that promote tourists' enjoyment of their bargaining adventure and ultimately enhance the overall shopping experience, the study reported in this article was aimed at identifying the dimensions underlying tourists' perceptions of the importance of 18 bargaining motivators and 12 bargaining attitudes and types of bargaining behavior, respectively, and subsequently evaluating the predictability of these underlying dimensions on tourists' shopping contentment indicators (overall bargaining satisfaction, the likelihood of a subsequent visit, and the likelihood of recommending open-air markets to others). A non-probability quota sampling technique was used to survey 203 Asian and non-Asian tourists in Hong Kong. A multivariate approach encompassing factor analysis and multiple regression was employed: Factor analysis delineated four underlying dimensions of factors affecting bargaining intentions. “Value for money” was shown to be the factor rated most important to tourists' bargaining intention; similarly, two underlying dimensions of bargaining attitudes and behavior—“bargain for psychological well-being” and “bargaining intensity”—were identified. Multiple regression results indicated the statistical significance of “bargaining for psychological well-being” and “bargaining intensity” to the existence of positive relations between shopping contentment indicators.     

Social risks and challenges in post-disaster resettlement: the case of Lake Nyos,Cameroon

This paper examines contemporary challenges in post-disaster resettlement in Cameroon. The focus is on the ongoing post-disaster experiences of survivors who were resettled in seven camps after the Lake Nyos Disaster in 1986. Empirical data obtained at the Ukpwa Waindo resettlement camp were used for analysis of impoverishment due to relocation and resettlement. Cameroon’s weak macroeconomic situation that started a quarter century ago had serious consequences for the country’s socio-economic trends, which is partly responsible for the slow recovery of disaster survivors. However, an analysis of social vulnerability using Cernea’s Impoverishment Risk and Reconstruction model shows how the involuntary resettlement of disaster survivors has itself created deep seated socio-economic and cultural consequences. By analysing their socio-economic situation, this article shows that resettlement is not merely a housing solution, but a complex, multi-dimensional process, with potentially very high negative impact if not properly planned and implemented. Therefore, the lessons learnt from this resettlement experience can be applied to ensure that resettlement becomes an opportunity to improve resilience and living conditions of the stricken population, and reduce exposure to disaster risk. There is urgent need for the government to tackle these long-term socio-economic problems faced by the disaster survivors, and to develop an effective policy to reconstruct, protect, improve or at least restore the livelihoods of those subject to resettlement.     

Some generalized distributions based on Stacy's generalized gamma distribution

Abstract

The generalized gamma distribution having the density function was introduced by Stacy (1962), who studied some of its properties. As observed by Stacy, many standard distributions are special cases of (1). For example d=p=1 gives the exponential, p=1 gives the gamma p=1 and d=n/2 (n is a positive integer) gives the chi-squared, and d=p gives the Weibull distribution. Furthermore, certain functions of a normal variable— viz., its positive even powers, its modulus, and all positive powers of its modulus, have Stacy's gamma form.
