Abstract
This study examines how antitrust law adoptions affect horizontal merger and acquisition (M&A) outcomes. Using the staggered introduction of competition laws in 20 countries, we find antitrust regulation decreases acquirers’ five-day cumulative abnormal returns surrounding horizontal merger announcements. A decrease in deal value, target book assets, and industry peers' announcement returns are consistent with the market power hypothesis. Exploiting antitrust law adoptions addresses a downward bias to an estimated effect of antitrust enforcement (Baker (2003)). The potential bias from heterogeneous treatment effects does not nullify our results. Overall, antitrust policies seem to deter post-merger monopolistic gains, potentially improving customer welfare.

Financial Technologies and the Effectiveness of Monetary Policy Transmission

Abstract
This study investigates whether and how financial technologies (FinTech) influence the effectiveness of monetary policy transmission. We use an interacted panel vector autoregression model to explore how the effects of monetary policy shocks change with regional-level FinTech adoption. Results indicate that FinTech adoption generally mitigates the transmission of monetary policy to real GDP, consumer prices, bank loans, and housing prices, with the most significant impact observed in the weakened transmission to bank loan growth. The relaxed financial constraints, regulatory arbitrage, and intensified competition are the possible mechanisms underlying the mitigated transmission.

Exports and private consumption weak ‒ Germany is waiting for an economic upturn
In the winter of 2023/2024, the German economy is still in a downturn. Parts of industry have lost competitiveness, real incomes have fallen in 2023 due to inflation, and there is uncertainty about the course of fiscal policy. However, rising real incomes and a slight increase in exports should cause a pickup from spring onwards. The Halle Institute for Economic Research (IWH) expects gross domestic product (GDP) to fall by 0.3% in 2023 and to expand by 0.5% in 2024 (East Germany: +0.5% and +0.7%). In September, the IWH forecast had assumed a decline of 0.5% for Germany in 2023 and expected growth of 0.9% for the coming year.

Microdata for Economic Research in Europe: Challenges and Proposals

No. 18640,
2023
Abstract
While access to high-quality microdata is essential for economic research and policy evaluation, effective access to such data remains limited in Europe. It varies from country to country, with uneven information on access procedures. This is a major obstacle to social science research, including research on European competitiveness and the effects of climate change, inequality, globalization, and digitalization. The objective of this paper, which is based on a brainstorming exercise coordinated by CEPR and CompNet, is to assess the status quo and discuss a series of proposals for improving access to Microdata for economic research. We underline the need for developing the relevant tools for extended access to and use of European business statistics microdata. Building such tools entails both establishing the requested microdata and creating a body facilitating cross-country access to the established databases with harmonized content.
