Comment on "Inflation Strikes Back: The Role of Import Competition and the Labor Market"
Mathias Trabandt
NBER Macroeconomics Annual,
2024
Abstract
Amiti et al. (2024) seek to answer a very topical and important research question: How much did supply-side disruptions and the tight labor market contribute to the recent surge in inflation? The answer provided by the authors is: about 2 percentage points. To arrive at their answer, the authors use a calibrated two-sector New Keynesian model in which they use three correlated shocks in a perfect-storm type setting. The paper also has an interesting empirical part that provides evidence that the channels emphasized in the theoretical model are at work in the data.

Import Competition and Firm Productivity: Evidence from German Manufacturing
Richard Bräuer, Matthias Mertens, Viktor Slavtchev
World Economy,
Nr. 8,
2023
Abstract
Abstract We study how different types of import competition affect firm productivity using firm-product data from German manufacturing (2000-2014). Competition from high-income countries causes affected domestic firms to increase their productivity and lower their prices. Oppositely, import competition from low-wage countries does not lead to firm productivity gains. Instead, domestic firms' sales and input usage decline. Our findings confirm the intuition of ladder models that the effect of competition depends on the "closeness" of competitors. They are in line with widespread X-inefficiencies throughout the economy, which firms reduce in response to competition from high-income countries.

Sources of Large Firms’ Market Power and Why It Matters
Filippo di Mauro, Matthias Mertens, Bernardo Mottironi
VOXEU COLUMN,
January
2023
Abstract
Excessive market power has detrimental effects on the functioning of the economy, raising consumer prices, distorting the allocation of resources, and creating welfare losses. The existing literature has largely focussed on competition in product markets. This column argues that it is important to differentiate between various sources of firm market power on output and input (most notably labour) markets. European firm-level data reveals that large firms charge lower markups in product markets but exert their market power significantly in labour markets. Competition authorities can and must distinguish between the sources of market power when attempting to regulate it.

The Urban Wage Premium in Imperfect Labor Markets
Boris Hirsch, Elke J. Jahn, Alan Manning, Michael Oberfichtner
Journal of Human Resources,
April
2022
Abstract
Using administrative data for West Germany, this paper investigates whether part of the urban wage premium stems from greater competition in denser labor markets. We show that employers possess less wage-setting power in denser markets. We further document that an important part of the observed urban wage premia can be explained by greater competition in denser labor markets.

Trade Shocks, Labour Markets and Elections in the First Globalisation
Richard Bräuer, Wolf-Fabian Hungerland, Felix Kersting
Abstract
This paper studies the economic and political effects of a large trade shock in agriculture – the grain invasion from the Americas – in Prussia during the first globalisation (1871-1913). We show that this shock accelerated the structural change in the Prussian economy through migration of workers to booming cities. In contrast to studies using today’s data, we do not observe declining per capita income and political polarisation in counties affected by foreign competition. Our results suggest that the negative and persistent effects of trade shocks we see today are not a universal feature of globalisation, but depend on labour mobility. For our analysis, we digitise data from Prussian industrial and agricultural censuses on the county level and combine it with national trade data at the product level. We exploit the cross-regional variation in cultivated crops within Prussia and instrument with Italian trade data to isolate exogenous variation.

Global Banking: Endogenous Competition and Risk Taking
Ester Faia, Sébastien Laffitte, Maximilian Mayer, Gianmarco Ottaviano
European Economic Review,
April
2021
Abstract
When banks expand abroad, their riskiness decreases if foreign expansion happens in destination countries that are more competitive than their origin countries. We reach this conclusion in three steps. First, we develop a flexible dynamic model of global banking with endogenous competition and endogenous risk-taking. Second, we calibrate and simulate the model to generate empirically relevant predictions. Third, we validate these predictions by testing them on an original dataset covering the activities of the 15 European global systemically important banks (G-SIBs). Our results hold across alternative measures of individual and systemic bank risk.

Finance-Growth Nexus and Banking Efficiency: The Impact of Microfinance Institutions
Afsheen Abrar, Iftekhar Hasan, Rezaul Kabir
Journal of Economics and Business,
March-April
2021
Abstract
This paper investigates the relative importance of microfinance institutions (MFIs) at both the macro (financial development, economic growth, income inequality, and poverty) and micro levels (efficiency of traditional commercial banks). We observe a significant impact on most of the fronts. MFIs’ participation increases overall savings (total bank deposits) and credit allocation (loans to private sector) in the economy. Their involvement enhances economic welfare by reducing income inequality and poverty. Additionally, their active presence helps to discipline the traditional commercial banks by subjecting them to more competition triggering higher efficiency.

Labor Market Power and the Distorting Effects of International Trade
Matthias Mertens
International Journal of Industrial Organization,
January
2020
Abstract
This article examines how final product trade with China shapes and interacts with labor market imperfections that create market power in labor markets and prevent an efficient market outcome. I develop a framework for measuring such labor market power distortions in monetary terms and document large degrees of these distortions in Germany's manufacturing sector. Import competition only exerts labor market disciplining effects if firms, rather than employees, possess labor market power. Otherwise, increasing export demand and import competition both fortify existing distortions, which decreases labor market efficiency. This widens the gap between potential and realized output and thus diminishes classical gains from trade.

Import Competition and Firm Productivity: Evidence from German Manufacturing
Richard Bräuer, Matthias Mertens, Viktor Slavtchev
Abstract
This study analyses empirically the effects of import competition on firm productivity (TFPQ) using administrative firm-level panel data from German manufacturing. We find that only import competition from high-income countries is associated with positive incentives for firms to invest in productivity improvement, whereas import competition from middle- and low-income countries is not. To rationalise these findings, we further look at the characteristics of imports from the two types of countries and the effects on R&D, employment and sales. We provide evidence that imports from high-income countries are relatively capital-intensive and technologically more sophisticated goods, at which German firms tend to be relatively good. Costly investment in productivity appears feasible reaction to such type of competition and we find no evidence for downscaling. Imports from middle- and low-wage countries are relatively labour-intensive and technologically less sophisticated goods, at which German firms tend to generally be at disadvantage. In this case, there are no incentives to invest in innovation and productivity and firms tend to decline in sales and employment.
