Using a sequential conditional independence assumption, this paper discusses fully nonparametric estimation of natural direct and indirect causal effects in causal mediation analysis based on inverse probability weighting. We propose estimators of the average indirect effect of a binary treatment, which operates through intermediate variables (or mediators) on the causal path between the...

This paper suggests a causal framework for disentangling individual level treatment effects and interference effects, i.e., general equilibrium, spillover, or interaction effects related to treatment distribution. Thus, the framework allows for a relaxation of the Stable Unit Treatment Value Assumption (SUTVA), which assumes away any form of treatment-dependent interference between study...

Changes in compulsory schooling laws have been proposed as an instrument for the endogenous choice of schooling. It has been argued that raising minimum schooling exogenously increases the educational attainment of a subset of pupils without directly affecting later life outcomes such as income or health. Using the method of Huber and Mellace (2015) and data from the Survey of Health, Ageing and...

This paper provides a review of methodological advancements in the evaluation of heterogeneous treatment effect models based on instrumental variable (IV) methods. We focus on models that achieve identification through a monotonicity assumption on the selection equation and analyze local average and quantile treatment effects for the subpopulation of compliers. We start with a comprehensive...

Research on leadership in economics has developed in parallel to the literature in management and psychology and links between the fields have been sparse. Whereas modern leadership scholars mostly focus on transformational and related leadership styles, economists have mainly emphasized the role of contracts, control rights, and incentives. We argue that both fields could profit from enriching...

People’s fairness preferences are an important constraint for what constitutes an acceptable economic transaction, yet little is known about how these preferences are formed. In this paper, we provide clean evidence that previous transactions play an important role in shaping perceptions of fairness. Buyers used to high market prices, for example, are more likely to perceive high prices as fair...

Drawing on research from design science, marketing and service science, our paper provides an integrated framework for evaluating and directing innovative service design. The main goal of our review is to highlight the strengths of existing frameworks and to suggest how they can be enhanced in combination with design science principles. Based on our review, we propose a new framework for the...

The conventional approach to monetary stability is not so much different from that related to price stability. As such, it simply supposes that the aggregation of prices in the marketplace is necessary and sufficient for determining the presence of inflation (or deflation) in the economy. However, investigating monetary stability according to this microeconomic approach leads to confusion since...

We investigate the dynamic effects of interregional labor market integration on migration flows, capital formation, and the price for housing services. The co-evolution of these variables depends on initial conditions at the time of labor market integration. In an initially capital-poor economy, there may be a reversal of migration flows during the transition to the steady state, while housing...

This documentation wants to be a "user manual" for the N-light-N framework. The goal is not only to introduce the framework but also to provide enough information such that one can start modifying and upgrading it after reading this document. This document is divided into five chapters. The main purpose of Chapter 1 is to introduce into our notation and formulation. It refers to further...
