This study critically examines HYBRIT, a Swedish flagship project led by state-owned LKAB to produce fossil-free sponge iron using hydrogen from fossil-free electricity. Framed as central to EU's green transition, HYBRIT promised CO₂ cuts exceeding Sweden's total emissions but faced major...

The transition to neighborhood-scale district heating in the Netherlands frequently stalls due to the challenge of achieving a collective agreement among individual homeowners. To explore the micro-dynamics of this collective action problem, this paper introduces an agent-based model that...

International environmental agreements (IEAs) often condition entry into force on ratification by a minimum number of countries, yet deep environmental commitments frequently face strong domestic political resistance. We study how IEA breadth, through minimum ratification thresholds (MRTs), and...

A growing literature concerns the role of symbolic politics, including how political parties benefit electorally from politicizing the past, a strategy which should be more effective in localities with physical memories of the past. We test this argument by studying the effect of the local...

Most empirical research on the effects of transparency on monetary policy committees is based on a natural experiment in 1993 at the Federal Reserve, when it was decided that transcripts of meetings would be released with a five-year lag. Evidence is found of both a conformity effect (reluctance...

We provide a rationale for Co-Voting, a decision-making procedure that blends elements of direct and representative democracy to mitigate their main inefficiencies. A randomly selected group of citizens receives voting rights on specific issues, with their collective decision aggregated with...

Green Deals have been introduced across Western economies as large-scale, mission-oriented innovation policies (MOIPs) intended to combine economic growth with environmental sustainability. Rooted in the concept of an "entrepreneurial state," these initiatives reflect renewed confidence in...

Environmental challenges increasingly shape political discourses across Europe, yet their influence on actual environmental governance remains unclear. This paper examines the political economy mechanisms linking environmental change, party platforms, and the decentralisation of environmental...

Why are inefficient policies popular? One explanation is incomplete voter information. Evidence from survey experiments in Argentina points instead to inattention. The experiments explore voter evaluations of two anti-inflation policies, price controls and limits on monetary emission....

We develop a model of monetary policy committee decision-making, building on the framework of games played through agents (GPTA). Interest groups seek to influence policy by offering action-contingent contracts to committee members. The resulting equilibrium admits a simple characterization and...

In a strategy-proof mechanism, implementation theory mostly assumes that each agent is rational in the sense that the agent reveals its true preference to induce its most preferred outcome. This assumption is sufficient to guarantee that the agent seeks such an outcome, but not necessary because...

We describe Aristotle's mathematical model of weighted voting to explain and implement decision-making in democracies, oligarchies and the mixed states that combine elements of both systems. This model, originally presented in textual form, extends the known history of social choice theory back...

Green Deals have been introduced across Western economies as large-scale, mission-oriented innovation policies (MOIPs) intended to combine economic growth with environmental sustainability. Rooted in the concept of an "entrepreneurial state," these initiatives reflect renewed confidence in...

This study examines the dynamics of economic freedom in nine advanced democracies in comparison to China over the 1970-2022 period. Using data from the Fraser Institute and the Manifesto Project Database, we apply a Bayesian time-series methodology to identify three key patterns. First, economic...

We study the communication strategies on Twitter/X of 367 political leaders in 21 countries, focusing on electoral competition between populists and non-populists. We measure polarization by the ease with which the leader can be classified as populist or not, conditional on his tweet. We find...

To what extent did class shape political behavior during early democratization and industrialization, and did class voting reflect economic interests or durable political identities? We use newly collected individual-level panel data from open-ballot elections in the nineteenth-century...

Hirschman's Exit, Voice, and Loyalty (1970) proposed that organizations persist when loyalty tempers incentives to exit after adverse shocks. We test this argument using newly digitized individual-level voting records from 28 English constituencies (1832-1868), covering 134,000 real votes....

James Buchanan would have celebrated his 100th birthday in 2019. This serves as an inspiration to look at the future of public choice and the question of how much normativity public choice can bear. In our analysis we draw parallels between public choice and German ordoliberalism (and its source...

Mission-oriented innovation policies are becoming increasingly popular among policymakers and scholars. We maintain that these policies are based on an overly mechanistic view of innovation and economic growth, suggesting that a more bottom-up approach is called for. By invoking an...

Cities increasingly address climate change, e.g. by pledging city-level emission reduction targets. This is puzzling for the provision of a global public good: what are city governments' reasons for doing so, and do pledges actually translate into emission reductions? Empirical studies have...

This paper investigates the causal effect of the term length of political executives on economic policy outcomes. To establish causality, we exploit the staggered adoption of four-year terms for governors across US states, using data for the period 1937-2008. We find that increasing governors'...

Cross-national parliamentary data have increasingly enabled scholars to study the behavior of individual Members of Parliament (MPs), allowing insights into issues such as (re)selection, intra-party dissent, and representation. Yet data on MPs' activity have largely been limited to speeches,...
