Political economy in finance

Political considerations have become important in finance research, with significant implications for policymaking. This column summarises new research presented at the CEPR conference on the Political Economy of Finance, including work on opaque investments in political influence, electoral impact of credit and regulation, the role of institutional complexity in shaping reforms and incentives of central bankers. The conference kickstarted the PolEconFin initiative aimed at providing a meeting point for researchers in this topical area.

This column reports on recent work presented at the first edition of the CEPR conference series on the Political Economy of Finance, which focused on the politics of regulation and central banking. The conference, held on 12 February 2021 and co-sponsored by three Dutch universities (Erasmus University Rotterdam, Tilburg University, University of Amsterdam), kickstarted the PolEconFin initiative ( The PolEconFin initiative comprises a conference series and an online platform, which allows researchers to share their work with a community interested in research on the political economy of finance.

Exploring political economy topics in finance research is still relatively new. The political economy of finance looks at how the design of political institutions and the distribution of political power in society affect the development and functioning of financial systems, and vice versa (see Pagano and Volpin 2001, Perotti 2014, Lambert and Volpin 2018 for surveys). 

Early research focused on topics such as political connections in firms (Fismann 2001, Khwaja and Mian 2005, Faccio 2006) or politically motivated changes in financial regulation and development (Kroszner and Strahan 1999, Biais and Perotti 2002, Bolton and Rosenthal 2002, Pagano and Volpin 2005, Perotti and von Thadden 2006). While these contributions appeared mostly in economic journals, finance journals also started opening up to this research area in recent years.

Figure 1 shows the number of articles published in the top-three finance journals (Journal of Finance, Journal of Financial Economics, Review of Financial Studies) that study questions related to the political economy of finance. Only a handful of articles were published in the mid-2000s, but interest rose following the financial crisis. The overwhelming majority of these publications is empirical work. Taking stock of research in this area reveals increasing awareness of the importance of political economy issues in finance but also reflects that the area is far from saturated.

Notes: We include in this set any articles published in top-three finance journals dealing with political institutions, electoral politics, and special-interest politics. We do not include articles on policy uncertainty and asset pricing unless the article connects with political institutions and power. The six Journal of Financial Economics articles of the pre-2002 period were published in 1990, 1994, 1996, 1998, and 1999 (x2).

The goal of PolEconFin is to connect researchers in this growing area and promote their work, and the first edition of the conference series was a successful start of this initiative.

Electoral politics, credit, and regulation

The electoral consequences of financial crises are well-documented. Yet the specific mechanisms through which financial crises affect elections remain elusive. Sartre et al. (2020) and Müller (2020) focus on some mechanisms.

Sartre et al. (2020) help understand how public finance mismanagement fuels the rise of populism during financial crises. Between 1996 and 2011, more than 1,500 French municipalities contracted high-risk structured loans with the bank Dexia. In September 2011, the newspaper Libération leaked a confidential file from Dexia, detailing all toxic loans it granted to municipalities. For the municipal elections following the leak, Sartre et al. (2020) find that affected municipalities saw a rise in populist voting and an increased entry of both far-right and far-left populist politicians. Far-right benefited more in areas with more fragile economic conditions and higher growth of the immigrant population.

Müller (2020) investigates how the design of policies contributes to politicians’ re-election prospects. He shows that macroprudential policies, supposed to curtail the risks of future financial crises, were systematically loosened in the run-up to 221 general elections across 58 countries. Politicians seem to do so because they do not want to cut off voters from access to credit.

Institutions, reforms, and politics

Policy reforms result from the complex interaction between various interest groups. In his keynote lecture (available here), Francesco Trebbi (Berkeley Haas) depicts the opaque and convoluted channels through which interest groups “invest in influence” and ultimately affect economic and policy outcomes. In particular, he highlights the important, albeit under-studied, role of localised charitable giving as a means of contributing to politicians (Bertrand et al. 2020a), donations to non-profits in exchange for regulatory advocacy (Bertrand et al. 2018a, 2018b), and firm acquisition as a tool to amplify political contributions of investors (Bertrand et al. 2020b).

The success (or failure) of interest groups in shaping policy reforms also depends on various features of political institutions. Foarta and Morelli (2020) study the problem of a regulator who receives imprecise information about the regulatory problem at hand. They find that overly complex reforms are implemented when regulators perceive the problem as complicated and are highly uncertain about the incentives of interest groups initiating reform proposals. 

However, the complexity of today’s reforms increases the difficulty of understanding future problems. In this context, Foarta and Morelli (2020) also show that variation in the starting institutional conditions may lead to drastically different regulatory paths: complexity traps, cycles of complexification-simplification, or regulatory gridlock.

Perotti and Soons (2019) study the political economy of the euro monetary area, seen as an arrangement among institutionally diverse economies. In their setup, politicians in institutionally weak countries need to spend more to remain in power, so in some states, they may have to devalue the currency to avoid a default. They find that a diverse monetary union implies an implicit fiscal transfer to strong countries due to devaluation, while fiscal capacity in weaker countries is reduced just as borrowing constraints are relaxed. A credible monetary union may require fiscal transfers from strong countries during crises, yet it can be mutually beneficial. Fiscal transfers thus represent a structural feature rather than a design flaw in a diverse monetary union (see Perotti and Soons 2020 for a non-technical summary).

Governance and central banking

After the financial crisis, central banks around the world saw their responsibilities further extended to financial stability domains (Masciandaro and Romelli 2015). Distributional choices are thus increasingly left in the hands of ‘unelected’ central bankers (Tucker 2019). Goncharov et al. (2020) and Fabo et al. (2021) uncover new stylised facts about central banks, which further challenge their political independence and accountability.

Goncharov et al. (2020) document the presence of a discontinuity in the distribution of central bank profits. Based on a sample consisting of 155 central banks over 23 years, they observe that central banks are more likely to report (small) profits than losses. Measures of political and market pressures as well as central bankers’ career concerns significantly predict small profits versus losses. Small positive profits are also associated with more lenient monetary policy and higher inflation. Together, these results suggest that central banks are concerned about the sign of their profits, probably for political reasons.

Fabo et al. (2021) compare research on the macroeconomic effects of quantitative easing produced by central-bank economists and academic economists (see Kempf and Pastor 2020 for a summary). Central-bank studies report quantitative-easing effects on output and inflation that are stronger and use more positive language in their studies compared to those written by academics. Moreover, central bankers whose studies report more significant effects of quantitative easing have better career outcomes. 

Fabo et al. (2021) also conduct a survey showing substantial involvement of bank management in research production and public distribution. However, the extent to which this involvement affects research outcomes remains a question open for future research.

PolEconFin: A platform for researchers

The 2021 edition of the CEPR conference series on the Political Economy of Finance only featured a few key advances but shows how fruitful and innovative the area is. It also stressed the importance of putting the political economy at the centre of finance research. As pointed out by Francesco Trebbi in his keynote lecture, the political economy of finance is about the reinforcing feedback loop between financial power, political power, and government policy. The by-products of the loop are top income inequality, stifled innovation and competition, sluggish productivity growth, and political pushback.

However, researchers active in the political economy of finance tend to be dispersed in discrete disciplinary areas, such as macroeconomics, public economics, economic history, law, or financial economics. Only a few other conferences are currently dedicated to research in this area, such as the London Political Finance Workshop (Beck et al. 2020). 

The PolEconFin platform seeks to provide a year-round meeting point for theorists and empiricists with shared interests in this topical area and build a research community with a focus on public policy.
