Investments in oil and gas fields are regressed against variables on panel field-data from the start of oil and gas production on the Norwegian continental shelf in 1968 until 2016. Two alternative models track the observed investments aggregated across fields from 1970 until 2016 relatively...

Assortment decisions are key strategic instruments for firms responding to local market conditions. We assess this claim by studying the effect of a national merger between two large Dutch supermarket chains on prices and on the depth as well as composition of assortment. We adopt a...

Using a difference-in-differences identification strategy on a micro panel at the bank and firm level, we study the transmission effectiveness of ECB’s large-scale asset purchasing programs programs (i.e. APP and PEPP) in the Euro area. Our findings show: first, balance sheet composition of...

We provide an evaluation of the impact of public subsidy schemes that aimed to support the development of basic broadband infrastructure in rural areas of Germany. Such subsidies are subject to state aid control by the European Commission (EC). While the EC increasingly recognises the role of...

We study the effect of a merger between two Dutch supermarket chains to assess its effect on the depth as well as composition of assortment. We adopt a difference-in-differences strategy that exploits local variation in the merger's effects, controlling for selection on observables through a...

This paper investigates firm dynamics in the period before, during, and after an event consisting of a first published patent application. The analysis is based on patent data from the Norwegian Industrial Property Office merged with data from several business registers covering a period of...

This paper examines the interaction between productivity growth, firms’ monopolistic market power, and workers’ wage bargaining power. Our study contributes to several strands of literatures. First, we examine a monopolistic framework which accounts for wage bargaining. In addition to the...

In this paper we employ survey information on more than 10,000 Southern and Eastern European firms and panel data methods to assess the effects of the COVID-19-related lockdown and government support policies on the business operations of enterprises. Our findings reveal considerable size- and...

We develop a novel methodology to quantify forecasts based on qualitative survey data. The methodology is generally applicable when quantitative information is available on the realization of the forecasted variable, for example from firm balance sheets. The method can be applied to a wide range...

In this paper, we extend Henning Bohn's (2008) fiscal sustainability test by allowing for slope heterogeneity and cross-sectional dependence (CD). In particular, our econometric approach is the first that allows fiscal reaction functions (FRF) to capture unobserved heterogeneous effects from...
