We propose a general equilibrium model with oligopolistic output markets where two channels can cause a change in market power: (i) technology, via changes to productivity shocks and the cost of entry, (ii) market structure, via changes to the number of potential competitors. First, we...

A workhorse two-country portfolio model that embeds net foreign asset (NFA) imbalances rationalizes the following observation: debtor countries have on average a less diversified international portfolio than creditor countries. Abstracting from NFA imbalances, the model would feature a...

The Digital Development Dialogue (3D) seminar is a monthly 45-minute online forum for policy and research exchange. Two speakers – one researcher and one practitioner – touch upon key topics in development policy with the goal of stimulating a meaningful dialogue across the theory & practice...

We estimate empirically the impact of the insolvency and bankruptcy code (IBC) on corporate leverage in India. The analysis builds on the Prowess database. For the estimations we use the difference in differences approach, where listed firms are used as the control group. We find that the IBC...

Economists typically make simplifying assumptions to make the solution and estimation of their highly complex models feasible. These simplifications include approximating the true nonlinear dynamics of the model, disregarding aggregate uncertainty or assuming that all agents are identical. While...

We examine the effect of regional favoritism on firms’ access to credit. Using firm-level data on a large sample of 29,000 firms covering 48 countries, we investigate the hypothesis that access to credit of firms is higher in the birth regions of national political leaders. We find evidence...

Doctoral supervision is becoming an important challenge for many institutions delivering management education at the doctoral level. The emergence of a global market for recruiting of Faculty members makes the quality of doctoral education and doctoral supervision in Management and Business...

We evaluate the impact of loan-to-value restrictions on household financial vulnerability. Using Norwegian tax data, we first document a beneficial leverage effect, in which households respond to the regulation by reducing house purchase probabilities, debt and interest expenses. Second, we...

We explore how firms grow by adding products. In contrast to most earlier work on the topic, our conceptual and empirical framework allows for separate treatment of product innovation (vertical differentiation) and diversification (horizontal differentiation). Chad Syverson Professor of...

What is the impact of granular credit risk on banks and on the economy? We provide the first causal identification of single-name counterparty exposure risk in bank portfolios by applying a new empirical approach on an administrative matched bank-firm dataset from Norway. Exploiting the fat...
