This paper estimates the demand for nature based tourist visits to Zambia and the willingness of international tourists to pay to visit Zambia using a single site individual travel cost model. The model estimated is corrected for both truncation of the dependent variable and endogenous stratification that arises due to on-site sampling. We find a negative binomial specification provides stable ...

The direction of the causality between energy consumption and income is an important issue in the fields of energy economics, economic growth, and policies toward energy use. The seminal work on the relations between energy consumption and aggregate income is Kraft and Kraft (1978). An extensive literature has followed on, including Akarca and Long (1980), Yu and Choi (1985), Erol and Yu (1988)...

The continuation of work that undermines employee well-being necessitates an investigation into the antecedents design. Therefore, we examined how autonomy supportive and controlling leadership—as defined in self-determination theory (SDT)—relate to employees’ job resources, demands, well-being. Using a cross-sectional ( N = 501) daily diary study 123), found leadership relates engagement via r...

In applied forecasting, there is a trade-off between in-sample fit and out-ofsample forecast accuracy. Parsimonious model specifications typically outperform richer model specifications. Consequently, there is often predictable information in forecast errors that is difficult to exploit. However, we show how this predictable information can be exploited in forecast combinations. In this case, o...

This research takes the analysis of the relationship between energy and income in a different direction than prior research, and it introduces a new set of analytical tools to the area. The results of our research are important because they raise additional questions about the effectiveness of income as a proxy indicator for standard of living, and these conclusions are supported by the use of ...

This paper considers methods for estimating the slope coe¢ cients in large panel data models that are robust to the presence of various forms of error cross section dependence. It introduces a general framework where error cross section dependence may arise because of unobserved common e¤ects and/or error spillover e¤ects due to spatial or other forms of local dependencies. Initially, this pape...

Abstract Wineries in the “old world” export almost 40% of their production. This study analyzes influence vertical and horizontal networks on performance. We draw a sample 183 Spanish wineries examine main independent variables using two-step Heckman model. find positive effects and—at somewhat lower level—downstream (JEL Classifications: L66, M16, Q13)

abstract this study investigates casual relationship between co2 emission and gross domestic product per capita in five different country groups, using cross- country data for the period 1960-2007. to achieve the purpose, the co- integration test and error correction models are applied. results confirm casual relationships between the two variables. a unilateral relationship between gdp and co2...
