This study examines how the economic e ects of elections in rural China depend on voter heterogeneity, as captured by religious fractionalization. We rst document religious composition and the introduction of village-level elections for a nearly nationally representative sample of over two hundred villages. Then, we examine the interaction e ect of heterogeneity and the introduction of election...

The impact of candidate campaign spending on votes and abstention in multiparty elections is estimated from the specification of a structural model of voter behavior. This model accounts for the endogeneity of campaign spending as well as the heterogeneity in voter preferences. Empirical results are estimated from aggregate (actual) election data using a standard Berry, Levinsohn and Pakes (199...

In the presence of capital accumulation the Taylor principle may not be sufficient for determinacy under reasonable parameter values. In this paper I consider a two-sector extension of the models used in the existing literature. I show that what matters for whether the Taylor principle is sufficient is the price stickiness of investment goods. Price stickiness of consumer goods on the other han...

Established enterprises continue to create new applications and systems without removing older ones. Legacy systems are often necessary to the new applications, but inadequate for the new environment, which can be large and widely distributed. This paper presents two applications—kiosks for telephone sales and support, and information access for service technicians—that are representative of a ...

Intensity profiles for helminths are used to describe population infection status, monitor effectiveness of control programs, and provide accurate data to validate transmission models. This study aims to accurately predict age/gender specific intensity profiles of endemic schistosomiasis japonica infection in the Philippines. Poor sensitivity of the Kato-Katz test and large heterogeneity in inf...

Cancer is a complex of many types of malignant neoplastic growths, and each cancer of each organ exhibits numerous subsets. Despite this heterogeneity, malignant neoplasms have a uniform characteristic—the ability to invade host tissues and produce metastases. The most fearsome aspect of cancer is metastasis. This fear is well based. There have been great improvements in diagnosis, general pati...

“Within” estimation of the fixed-effect stochastic frontier model does not identify parameters on time-invariant explanatory variables. If time-invariant variables are important production inputs, then standard efficiency estimates are biased. This note details bias correction, when time-invariant inputs are dummy variables. © 2006 Elsevier B.V. All rights reserved.

In this paper the regression problem for random sets of the Boolean model type is developed, where the corresponding poisson process of the model is related to some explanatory variables and the random grains are not affected by these variables. A model we call propagation model, is presented and some methods for fitting this model are introduced. Propagation model is applied in a simulation st...

this paper tests the importance of real shocks as sources of fluctuations in iran’s economy. for this purpose, based on the work of boschen and mills, a set of non-monetary variables which can affect economic growth have been selected and by using an illustrative business cycle model in which the production depends on the past and current value of real shocks, the influence 01’ these variables ...

The relationship between elastic wave velocities and water saturation in a water/gas reservoir depends strongly on whether saturation is heterogeneous (patchy) or homogeneous. Heterogeneity in saturation may result from lithologic heterogeneity because under conditions of capillary equilibrium, different lithologies within a reservoir can have different saturations, depending on their porositie...
