A purposive sample of South African doctors provided data for the analysis of revenues, costs and earnings associated with specialist surgical medicine. Empirical analysis of the data, based on both nonparametric and parametric regression, finds that practice revenues increase by, on average,...

The heavy dependence and inefficient utilization of biomass resources for energy have resulted in high depletion of the forest resources in Ethiopia, while the use of traditional cooking technology, one source of inefficient biomass resource use, has been linked to indoor air pollution and poor...

This study examines the relationship between property rights, defined by land tenure security, the strength of local-level institutions, and household demand for fuel wood, as measured by the source from which fuel wood is collected. A multinomial regression model is applied to survey data...

This study examines the role of local level institutions and property right regimes on the forest-poverty link, with respect to non-wood forest products, using data from a random sample of rural households in Ethiopia. Households in the sample derive approximately 8.7% of their income from these...

We empirically investigate the hypothesis that when democracies are young, or still fragile and unconsolidated, the size of government (in terms of consumption, debt and share to GDP) tends to increase in an attempt to buy out the electorate, so that democracy becomes acceptable and ?the only...

This paper, first, estimates the appropriate, log-log or semi-log, linear long-run money demand relationship capturing the behavior US money demand over the period of 1980:Q1 to 2010:Q4, using the standard linear cointegration procedures found in the literature, and the corresponding...

This paper analyses the intertemporal hedging demand for stocks and bonds in South Africa (SA), the United Kingdom (UK) and the United States (US). The analysis is done using an approximate solution method for the optimal consumption and wealth portfolio problem of an infinitely long-lived...

We compare the forecasting performances of the classical and the Minnesota-type Bayesian vector autoregressive (VAR) models with those of linear (fixed-parameter) and nonlinear (time-varying parameter) VARs involving a stochastic search algorithm for variable selection, estimated using Markov...

In this study, welfare impacts associated with a unique common-property forestry program in Ethiopia were examined. This program is different from other programs, because it is two-pronged: a community forest is developed and additional support is provided for improved market linkages for the...

This study examines the potential for anomalous response behaviour effects within the context of double-bounded contingent valuation methods applied to community forestry programs in rural Ethiopia. Anomalous responses considered include shift effects, framing effects and anchoring effects, and...
