How do shifts in the global balance of power shape the world economy? We propose a theory of alignment-based “hegemonic globalization,” built on two central premises: countries differ in their preferences over policies (such as the rule of law or regulatory frameworks) and trade between any two countries increases with the degree of alignment in these policies. Hegemons promote policy alignment and ...

Do trade dependencies leave countries vulnerable to geopolitical coercion? We study the economic costs of trade and financial sanctions, from 1920 to the present. We first develop a continuous measure of sanction intensity, using bilateral commodity-level data to calculate the importance of specific flows that fall under sanctions. We find that sanctions inflict relatively small costs on average: sanctioning ...

Between 1950 and 2023, the housing cost burden — approximated by the proportion of total household consumption expenditure spent on housing, water, electricity and fuel — has risen almost steadily in many countries around the world. First, this trend can be explained by substantial improvements in the quantity and quality of housing. In fact, in some countries (e.g., Germany), per capita floor space ...

We study how rent control and housing rationing shape housing investment and market tightness in Geneva using a VAR on annual data (1994–2022) with generalized impulse responses and Granger causality. We find that housing rationing functions as a binding quantity restriction as it precedes a contraction in new institutional construction and Granger-causes lower vacancy rates. This increased scarcity ...

I study the transmission mechanism of Quantitative Easing (QE) in the form of large-scale asset purchases in the mortgage market to aggregate consumption. To this end, I develop a New Keynesian model that features heterogeneous households, a microfounded housing market, and frictional intermediation. This model helps explain the empirical evidence suggesting that QE increases aggregate consumption ...

We study the effects of movements in aggregate lending standards on macroeconomic aggregates and inequality. We show in a New Keynesian model with heterogeneous households and housing that a looser loan-to-value (LTV) ratio stimulates housing demand, nondurable consumption, and output. Our model implies that the LTV shock transmits to macroeconomic aggregates through higher household liquidity and ...

Stock market participation among working household heads jumped upwards in 2020 – in Germany by about 25%. A major cause is the required use of work from home (WfH). We show this by adding WfH to a large set of explanatory variables. Moreover, we implement an instrumental variables estimation based on industry-specific levels of WfH-capacity. The transmission channels seem to work via increased available ...

This paper investigates the effectiveness of the European Central Bank’s (ECB) communication in shaping market expectations and real economic outcomes. Using a transformer-based large language model (LLM) fine-tuned to ECB communication, the tone of monetary policy statements from 2003 to 2025 is classified, constructing a novel ECB Communication Stance Indicator. This indicator contains forward-looking ...

DIW Discussion Papers 2132 / 2025
Attitudes toward fiscal policy differ: fiscal conservatism and fiscal liberalism vary in their willingness to tolerate budget deficits. We challenge the view that such attitudes reflect national preferences. Instead, we offer an economic explanation based on a two-country Heterogeneous Agent New Keynesian model, bringing its implicit political economy dimension to the forefront. We compute the welfare ...

This paper provides causal evidence on the effect of credit crunches on political polarisation. Combining data on bank-firm connections and electoral outcomes at the city-level during the 2008-2014 Spanish financial crisis, I construct an instrument for unemployment based on the city-level exposure to (foreign) weak banks. I find that a 10% increase in (instrumented) local unemployment rates leads ...
