Estimation procedures for ordered categories usually assume that the estimated coefficients of independent variables do not vary between the categories (parallel-lines assumption). This view neglects possible heterogeneous effects of some explaining factors. This paper describes the use of an...

Background: Subjective health status and migration are critical issues in healthcare policy and strategic decision making. There are many health challenges to resolve and at the same time, migration has reached to historic highs, leading to different views among immigrants and natives, policy...

This paper analyzes the patient characteristics that affect the choice between public and private health care providers in Istanbul, Turkey. In addition to socioeconomic variables, such as insurance status or income, which have often been considered in the previous literature, we also focus on...

Using the four-year academic records of 301 male students who enrolled in a specific department at a certain university in April 2016, this paper estimates the structural parameters of a sequential decision model of college dropout and conducts a counterfactual analysis. A well-known method for...

We consider two popular classes of volatility models, the generalized autoregressive conditional heteroscedastic (GARCH) model and the stochastic volatility (SV) model. We compare these two models with two classes of intensity models, the integer-valued GARCH (INGARCH) model and the...

We formulate a model of reference-dependent preferences based on the marginal rate of substitution at the reference-point of a reference-free utility function. Using binary choices on the trade-off between money and travel time, reference-dependence is captured by value functions that are...

In discrete choice models the marginal effects of a variable that is interacted with another variable and the interaction term differ from the marginal effect of a variable that is not interacted with any variable. Standard software incorrectly estimates these marginal effects. I provide correct...

ABSTRACT: Recently, most European manufacturing firms have been engaged in a number of innovative activities to survive the growing competition coming from newly-industrialising countries. Italian manufacturing industry, which relies largely on SMEs, is struggling to regain competitiveness in...

Abstract: In this paper we assess the relevance of both knowledge creation and diffusion processes in affecting Italian SMEs’ propensity to innovate. In doing so a knowledge production function (KPF) is estimated for a representative sample of small and medium manufacturing firms over the...
