| Random Utility Models of recreation demand are widely used to relate demand and value to the characteristics of recreation sites. Although some kinds of endogeneity problems have been studied in previous literature, no study has addressed the potential problem with site characteristics that are endogenously supplied. Some site characteristics, like facilities, could be endogenous in an economic sense due to the interplay of supply and demand. That is, more popular recreation sites tend to have better site characteristics since managers with limited budgets would be more willing to invest in them. If recreation site improvements are more likely to occur at the more popular sites, then this economic endogeneity might cause problems for econometric models... |

| Different kinds of endogeneity problems in Random Utility Models of recreation demand have been studied in previous literature. Some site characteristics, like facilities, could be endogenous in an economic sense due to the interplay of supply and demand. That is, it may be that more popular recreation sites tend to have better site characteristics since managers with limited budgets would be more willing to invest in them. If recreation site improvements are more likely to occur at the more popular sites, then might this economic endogeneity cause problems for econometric models linking site demand to facilities. In this paper, we use Monte Carlo simulations to test whether this economic endogeneity will lead to statistical endogeneity. |

| Using comprehensive rural farm household longitudinal data from Zambia, this paper measures the impacts of prime-age (PA) adult morbidity and mortality on crop production and cropping patterns, household size, livestock and non-farm income. The paper adopts and extends the counterfactual (difference-in-difference) approach by controlling for initial (pre-death) household conditions that may influence the severity of the impacts of adult mortality. In particular, the study controls for initial poverty status, landholding size, effective dependency ratios, and the gender and position of the deceased person. Moreover, the possibility that PA death in the household is endogenous is taken into account by conceptualizing the measurement of effects of... |

| In this paper, we develop an empirical test of consistency in contingent willingness to pay (WTP) responses, which is based on the following a priori expectation. In economics, when an individual considers paying for public goods, his decision to pay, and his WTP are based on utility-maximising behaviour. Accordingly, supposing other factors are identical, if individual A expresses greater interest in paying for public goods in general than individual B, that is because A receives more benefits from the use and/or the non-use of these goods than B. Continuing with this logic, if both individuals are asked about their WTP for a precise public good, A should logically be more likely to pay and should be willing to pay more than B. Thus, the test consists in... |

| The objective of this article is to investigate why farmers in Kosovo leave land fallow when the total land of their farms is small and households, almost fully dependent on farming for their livelihoods, are large. In order to elicit some of the barriers to land utilization, the article uses a comprehensive survey carried out during the agricultural year 2005/2006 to explore agricultural households’ perceptions of production, market conditions, and general security six years after the end of the military conflict in the former Yugoslavia. Several agro-environmental, household and farm characteristics are employed to empirically approximate the significance of different factors for leaving land fallow. Three different econometric models are used to address... |

| A key issue in the estimation of production functions is the correlation between unobservable productivity shocks and input levels. Profit-maximizing firms respond to positive productivity shocks by expanding output, which requires additional inputs. Negative shocks lead firms to pare back output, decreasing their input usage. Olley and Pakes (1996) develop an estimator that uses investment as a proxy for these unobservable shocks. More recently, Levinsohn and Petrin (2003a) introduce an estimator that uses intermediate inputs as proxies, arguing that intermediates may respond more smoothly to productivity shocks. This paper reviews Levinsohn and Petrin’s approach and introduces a Stata command that implements it. |
