The impact of climate change on labour demand in the plantation sector: the case of tea production in Sri Lanka

Limited opportunities for crop switching and lengthy preharvesting periods make the plantation sector particularly vulnerable to climate change. Surprisingly, however, the economic consequences of climate change on plantation crops are seldom analysed. Drawing on a unique primary panel data set from a representative cross section of 35 tea estates in Sri Lanka over the period 2002–2014, this study implements a structural model of estate profit maximisation to estimate the elasticity of labour demand with respect to different components of weather. Results indicate a negative relationship between labour demand and rainfall in the south‐west monsoon, the north‐east monsoon and the second inter‐monsoon. A positive relationship is found between labour demand and rainfall in the first inter‐monsoon. Overall, predicted changes in rainfall by 2050 are anticipated to reduce labour demand by approximately 1,175,000 person‐days per year across Sri Lanka's tea plantation sector. This is likely to have considerable social and welfare implications, particularly for the Indian Tamil women who comprise the majority of the sector's workforce.     

Country of Origin Labeling and Structural Change in U.S. Imports of Canadian Cattle and Beef

Mandatory country of origin labeling (COOL) has become a thorny issue in U.S.–Canada bilateral trade relations. We undertake an ex post investigation of the impact of the law on U.S. imports of Canadian beef, feeder, and fed cattle. Using a partial equilibrium framework, we derive U.S. import demand equations for Canadian cattle and beef, and employ the Bai and Perron (1998, 2003) procedure for detecting multiple structural breaks with break points being endogenously determined. We find evidence that COOL may have caused significant structural change in U.S. imports of Canadian feeder and fed cattle. L’étiquetage du pays d'origine obligatoire est devenu un sujet épineux des relations commerciales entre le Canada et les États‐Unis. Dans la présente étude, nous effectuons une analyse ex post des répercussions de la Loi sur les importations américaines de viande de b?uf, de bovins d'engraissement et de bovins finis. À l'aide d'un modèle d’équilibre partiel, nous avons dérivé des équations de demande d'importation de bovins et de viande de b?uf de la part des États‐Unis et nous avons utilisé les tests de Bai et Perron (1998, 2003) pour déceler les ruptures structurelles multiples, dont les points de rupture ont été déterminés de façon endogène. Les résultats de notre étude montrent que l’étiquetage du pays d'origine peut avoir causé un changement structurel considérable sur les importations de bovins d'engraissement et de bovins finis.     

Tourists’ hotel event experience and satisfaction: an integrative approach

ABSTRACT

Tourists’ hotel event experiences have received little attention in tourism research. By proposing an integrated model of expectation–confirmation theory (ECT) and the experience economy concept, this research explores the relationship between tourists’ event experience and their satisfaction regarding the hotel event setting. The hypothesized model was empirically validated using a sample of 663 tourists who experienced a holiday event at a resort hotel. Results confirmed that the integration of the experience economy and ECT provided a better understanding of tourists’ post-satisfaction in a pleasure-driven setting. This affective–cognitive approach advances the knowledge of tourists’ experiences and satisfaction at hotel events.     

Correlation of acid gas-ethanolamine equilibrium using ionic concentrations

Experimental equilibrium measurements are modeled using a Davies-like ionic strength correction term for the reaction equilibrium constants. Calculated and experimental results are in much better agreement when the ionic strength correction terms are used.     

Contribution of low-level flammable vapor concentrations to dust explosion output

As a result of extensive dust explosion research, additional areas of hazards have arisen. The potential of combining small percentages of flammable vapors (below the lower explosion limit) introduces additional dust explosion hazards.     

Personal Attachment to the Union in Small Bargaining Units

Union member attachment research has generally examined large unions organizing large employers. The present study presents a conceptual model and related data concerning various aspects of the union attachment expressed by individuals in small bargaining units. The results show differences among individuals in commitment based on their union experiences and demographic characteristics. Résumé Les études traitant de la loyatué qu'éprouvent les membres envers leur syndicats examinent généralement des syndicats importants au sein d'entreprises de taille. La présente étude offre un modèle conceptuel et les données relatives aux divers aspects de la loyauté exprimée par des individus appartenant à de petites unités de négociations. Les résultats démontrent les différences de loyauté chez les membres selon leur experience syndicale et les caractéristiques démographiques.     

Tests of Hypotheses Arising In the Correlated Random Coefficient Model

This paper examines the correlated random coefficient model. It extends the analysis of Swamy (1971), who pioneered the uncorrelated random coefficient model in economics. We develop the properties of the correlated random coefficient model and derive a new representation of the variance of the instrumental variable estimator for that model. We develop tests of the validity of the correlated random coefficient model against the null hypothesis of the uncorrelated random coefficient model.

Risk premia in forward exchange rates: systematic or unsystematic?

International traders frequently use forward exchange transactions to hedge their cash flows in foreign currencies. A key issue is whether the forward rates are efficiently priced. There is evidence of time-varying risk premia in forward exchange rates. Are these risk premia systematic or unsystematic? This article uses a market model to explain risk, implying that the risk premium in the forward rate varies pari passu with the beta of the return to speculative forward positions. Assuming the unobserved risk premium is proportional to the forward premium allows testing the predicted relations; the data reject the joint hypotheses of the model and systematic risk. In terms of a simple factor model explaining the covariation of the forward premium, the risk premium, and the expected percentage rate of change of the spot exchange rate, the assumption that the forward premium and the risk premium are proportional can be relaxed without changing the empirical results.     

Estimating Willingness to Pay for the Development of a Peace Park Using CVM: The Case of the Korean Demilitarized Zone

Conflicts remain an integral part in shaping the world. Tensions on the Korean Peninsula are no exceptions. The Korean DMZ (Demilitarized Zone) World Peace Park has been proposed to help obtain peace by erasing the memories of war and creating new beginnings of trust, cooperation, and unity on the Korean Peninsula. With their ties to geographical space and conflict, peace park research provides an excellent platform for both activism and research in positive peace. Little, however, is known about peoples’ willingness to pay (WTP) for the creation of peace parks, in general, and specifically for the development of the Korean DMZ World Peace Park. Using contingent valuation methods, the weighted average WTP for development of the Peace Park is $49.03 per household per year. It appears South Koreans are willing to pay not only for the conservation of the DMZ, but also for the peace and unification of the Korean Peninsula the Peace Park may bring to the area.
