Why IT Matters: An Empirical Study of E-Business Usage, Innovation, and Firm Performance
Köllinger, Philipp - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2005
The article argues that IT continues to have strategic relevance for companies because it en-ables innovation. A … conceptual link between the adoption of IT and innovation is established. This conceptual link allows a market-based, economic … explanation for variations in IT payoffs among firms: The successful adoption of new IT leads to innovation. Depending on the be …

The Rise in Absenteeism: Disentangling the Impacts of Cohort, Age and Time
Biorn, Erik; Gaure, Simen; Markussen, Simen; Røed, Knut - Institute for the Study of Labor (IZA) - 2010
We examine the remarkable rise in absenteeism among Norwegian employees since the early 1990's, with particular emphasis on disentangling the roles of cohort, age, and time. Based on a fixed effects model, we show that individual age-adjusted absence propensities have risen even more than...

Identification and Estimation in Discrete Choice Demand Models when Endogenous Variables Interact with the Error
Gandhi, Amit; Kim, Kyoo il; Petrin, Amil - National Bureau of Economic Research (NBER) - 2011
We develop an estimator for the parameters of a utility function that has interactions between the unobserved demand error and observed factors including price. We show that the Berry (1994)/Berry, Levinsohn, and Pakes (1995) inversion and contraction can still be used to recover the mean...

Partial Identification of Heterogeneity in Preference Orderings Over Discrete Choices
Fox, Jeremy; Sher, Itai; Kim, Kyoo il; Bajari, Patrick - National Bureau of Economic Research (NBER) - 2011
We study a variant of a random utility model that takes a probability distribution over preference relations as its primitive. We do not model products using a space of observed characteristics. The distribution of preferences is only partially identified using cross-sectional data on varying...

A long-run survival analysis of corporate liquidations in Ireland
Kelly, Robert; O'Brien, Eoin; Stuart, Rebecca - Central Bank of Ireland - 2014
This paper examines the role of credit and the macroeconomy in SME distress during a pro- longed economic downturn. Specically, we estimate the determinants of SME distress in Ireland during the severe financial and economic crisis which began in 2007/2008. We use a measure of dis- tress,...

A Simple Nonparametric Estimator for the Distribution of Random Coefficients
Fox, Jeremy; Ryan, Stephen P.; Bajari, Patrick; Kim, Kyoo il - National Bureau of Economic Research (NBER) - 2009
We propose a simple nonparametric mixtures estimator for recovering the joint distribution of parameter heterogeneity in economic models, such as the random coefficients logit. The estimator is based on linear regression subject to linear inequality constraints, and is robust, easy to program...

Identifying Heterogeneity in Economic Choice Models
Fox, Jeremy; Gandhi, Amit - National Bureau of Economic Research (NBER) - 2009
We show how to nonparametrically identify the distribution that characterizes heterogeneity among agents in a general class of structural choice models. We introduce an axiom that we term separability and prove that separability of a structural model ensures identification. The main strength of...

Identification and Estimation of Discrete Choice Demand Models when Observed and Unobserved Characteristics are Correlated
Petrin, Amil; Ponder, Mark; Seo, Boyoung - National Bureau of Economic Research - 2022
The standard Berry, Levinsohn, and Pakes (1995) (BLP) approach to estimation of demand and supply parameters assumes that the product characteristic observed by consumers and producers but not the researcher is conditionally mean independent of observed characteristics. We extend BLP to allow...
