This paper quantifies the origins of firm size heterogeneity when firms are interconnected in a production network. Using the universe of buyer-supplier relationships in Belgium, the paper develops a set of stylized facts that motivate a model in which firms buy inputs from upstream suppliers...

For a finer analysis of global value chain integration and competitiveness, we develop and apply a method for a micro-data based breakdown of manufacturing industries in the 2010 Belgian supply-and-use tables into export-oriented and domestic market firms. The former are defined as those firms...

The paper traces labor market reforms over the last four decades. It provides estimates of retirement incentives for a selected set of typical worker profiles across time and socioeconomic groups and links these series to the labor market performance in Belgium. The results show that the...

We estimate the impact of the COVID-19 crisis on business failures among small and medium size enterprises (SMEs) in seventeen countries using a large representative firm-level database. We use a simple model of firm cost-minimization and measure each firm's liquidity shortfall during and after...

To assess age-specific infection fatality rates (IFRs) for COVID-19, we have conducted a systematic review of seroprevalence studies as well as countries with comprehensive tracing programs. Age-specific IFRs were computed using the prevalence data in conjunction with reported fatalities four...

Using new data on currency invoicing for Belgian firms, we analyze how firms make their currency choice, for both exports and imports, and the implications of this choice for exchange rate pass-through into prices and quantities. We derive our estimating equations from a theoretical framework...

This paper assesses the prospects of a 2021 time bomb in SME failures triggered by the generous support policies enacted during the 2020 COVID-19 crisis. Policies implemented in 2020, on their own, do not create a 2021 "time-bomb" for SMEs. Rather, business failures and policy costs remain...

In this paper I analyze the productivity gains from trade liberalization in the Belgian textile industry. So far, empirical research has established a strong relationship between opening up to trade and productivity, relying almost entirely on deflated sales to proxy for output in the production...

The objective of this paper is twofold. First, we analyse the structure of wages within and between Belgian firms. Next, we examine how the productivity of these firms is influenced by their internal wage dispersion. To do so, we use a large matched employer-employee data set (i.e., a...

This paper proposes a framework to account for innovation similar to the usual accounting framework in production analysis and a measure of innovativity comparable to that of total factor productivity. This innovation accounting framework is illustrated using micro-aggregated firm data from the...
