I show that sharp identified sets in a large class of econometric models can be characterized by solving linear systems of equations. These linear systems determine whether, for a given value of a parameter of interest, there exists an admissible joint distribution of unobservables that can...

The estimation of the holding periods of financial products has to be done in a dynamic process in which the size of the observation time interval influences the result. Small intervals will produce smaller average holding periods than bigger ones. The approach developed in this paper offers the...

This paper considers identification and estimation of the Quantile Treatment Effect on the Treated (QTT) under a straightforward distributional extension of the most commonly invoked Mean Difference in Differences Assumption used for identifying the Average Treatment Effect on the Treated (ATT)....

Adequate supervision (control) of the functioning of voluntary pension insurance is one of the preconditions for the development of this form of insurance. The primary objective of supervision is to protect insured persons and insurance beneficiaries by providing conditions for unhindered and...

Economic development is characterised by the fact that the share of agriculture tends to decrease both in terms of resources used and domestic product generated. This does not mean, however, that the role of agriculture in the economic development diminishes. It can be considered a paradox that...

We put forward a brand choice model with unobserved heterogeneity that concerns responsiveness to marketing efforts. We introduce two latent segments of households. The first segment is assumed to respond to marketing efforts, while households in the second segment do not do so. Whether a...

This study extends prior research on referee bias and close bias in professional soccer by examining whether Major League Soccer (MLS) referees’ discretion over stoppage time (i.e., extra play beyond regulation) is influenced by end-of-regulation match scores and/or home field advantage. To do...

This paper utilizes a joint (ordered probit) occupational attainment and wage determination model to examine the channels through which occupational segregation and pay discrimination affect the overall gender wage gap in different sectors of ownership in Egypt. Using a large data set drawn from...

The paper addresses a topical issue - how expansionary fiscal policy affects the debt to GDP ratio. It examines whether the projected future economic growth (stimulated by government spending) is sustained with the resulting national debt. It is discussedif government investment in...
