An economic signalling model contributing to the explanation of religious schism is presented. Religious groups are interpreted as a device for exchanging information about and via others. Two effects result. First, the larger the network, the worse the signal quality one receives of the type of...

In this paper we aim to analyze the productivity spillovers of foreign affiliated and domestic firms in Turkish manufacturing industries. As a novelty inter-sectoral linkages are modeled through the use of spatial models. Our results indicate the existence of positive and significant...

The aim of this paper is to analyze the extent of network effects in mobile telecommunications in Turkey, and to identify other determinants of consumer choice based on consumer survey data. This study shows that there are regional disparities in the adoption of network services in Turkey, the...

This paper evaluates the forecasting ability of alternative product growth models for telecommunication services in Turkey. The variable exponential growth model better explains the diffusion process of fixed line services, suggesting that S-shaped models are not able to model the period of the...

In this paper we present an economic model contributing to the explanation of religious schism, a topic mostly dealt with in the fields of sociology and psychology so far. The main idea is to see religious groups as networks. These networks may serve as a device for exchanging information about...

This paper estimates demand elasticities for Turkish mobile telecommunications markets. In contrast to most other studies, firm-level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a...

We explore maximum likelihood (ML) estimation of the Hildreth-Houck random coefficients model. We show that the global ML estimator can be inconsistent. We develop an alternative LML (local ML) estimator and prove that it is consistent and asymptotically efficient for points in the interior of...

Purpose – The purpose of this paper is to argue that corruption is inherently unmeasurable. Measures of corruption produced by different sources are highly unsatisfactory. Useful measures may be possible for specific purposes in limited contexts. Reasons why highly unsatisfactory measures are...

We draw on a newly collected historical dataset of fiscal variables for a large panel of countries—to our knowledge, the most comprehensive database currently available—to gauge the degree of fiscal prudence or profligacy for each country over the past several decades....
