This article estimates the visitation demand function for Kgalagadi Transfrontier Park (KTP) in
order to determine the scope for raising fees charged to international tourists in order to fund
revenue-sharing schemes for local communities. International and Southern African Development
Community tourists account for approximately 25% and 2% of the total number of visitors to
South African national parks, with domestic visitors making up the remaining portion. Although
Individuals’ risk preferences may change after experiencing external socio-economic or natural shocks. Theoretical predictions and empirical studies suggest that risk taking may increase or decrease after experiencing shocks. So far the empirical evidence is sparse, especially when it comes to developed countries. We contribute to this literature by investigating whether experiencing financial and health-related damage caused by storms affects risk preferences of individuals in Germany.
We investigate the role of an indigenous social network in Ethiopia, the iddir, in facilitating factor market transactions among smallholder farmers. We use detailed longitudinal household survey data and employ fixed effects estimation approaches to identify the effect of iddir membership on factor market transactions among farmers. We find that joining an iddir network improves households’ access to land, labour and credit transactions.
We estimate the production function for agricultural output in Eastern Africa incorporating climate variables disaggregated into growing and non-growing seasons. We find a substantial negative effect of within growing season variance of precipitation. We simulate predicted climate change for the region and find a resulting output reduction of between 1.2% and 4.5%.
Pay-What-You-Want (PWYW) pricing schemes are becoming increasingly popular. We develop a model incorporating self-image into the buyer’s utility function and introduce heterogeneity in consumption utility and image-sensitivity, generating different purchase decisions and optimal prices across individuals. When a good’s fixed price is lower than a threshold fair value, PWYW can lead to a lower utility. This may result in a lower purchase rate and higher average price, accounting for previously unexplained field experimental evidence.
In this paper, we propose a reputation-signalling model of demand for consumer goods containing pro-social characteristics such as a ‘fair trade’ or ‘organic’ certification. We show that reputation signalling can reverse price reactions resembling the crowding-out of pre-existing motives for pro-social behavior seen in situations of volunteering and charitable giving. Finally, using a unique combination of questionnaire and purchase panel data, we present evidence of such reputation-driven reversal of price reactions in the Danish market for organic milk.
We present a novel policy framework to evaluate and pursue growth in aquaculture considering four boundaries: biological productivity, environmental constraints to that productivity, policy that inhibits or promotes different kinds of aquaculture, and social preferences that determine aquaculture markets.
The adoption of good practices for the economic valuation of environmental services (ES) has strong implications in the evaluation and design of a Payment for Environmental Services program.
The authors used a Bayesian estimation approach to estimate a quantile binary regression and the WTP distribution in the context of a contingent valuation PES application.
City is the major energy user and emission source in China,which accounts for 70% of total energy consumption. To achieve the sustainable development, China need to further boost the urban development while lower the huge energy demand. Will the accelerating urbanization process lead to higher energy demand? This issue raises intensive attention from the decision-makers, public, and academic society. Most previous studies concluded that the urbanization is positively associated with household energy demand.
