### Debating the merits of large- and small-N studies

Sample size does more than determine the sort of methodology appropriate for a given study; theorists of social science have long pointed out that the number of case studies considered determines the sorts of questions researchers can analyze and the structure of their causal claims.

A 2003 paper by PETER HALL takes these debates further. In the context of comparative political science, Hall argues that the sort of methods researchers use should be consistent with their beliefs about the nature of historical development. From the paper:

"Ontology is crucial to methodology because the appropriateness of a particular set of methods for a given problem turns on assumptions about the nature of the causal relations they are meant to discover. It makes little sense to apply methods designed to establish the presence of functional relationships, for instance, if we confront a world in which causal relationships are not functional. To be valid, the methodologies used in a field must be congruent with its prevailing ontologies. There has been a postwar trend in comparative politics toward statistical methods, based preeminently on the standard regression model. Over the same period, the ontologies of the field have moved in a different direction: toward theories, such as those based on path dependence or strategic interaction, whose conceptions of the causal structures underlying outcomes are at odds with the assumptions required for standard regression techniques.

The types of regression analyses commonly used to study comparative politics provide valid support for causal inferences only if the causal relations they are examining meet a rigorous set of assumptions. In general, this method assumes unit homogeneity, which is to say that, other things being equal, a change in the value of a causal variable x will produce a corresponding change in the value of the outcome variable y of the same magnitude across all the cases. It assumes no systematic correlation between the causal variables included in the analysis and other causal variables. And most regression analyses assume that there is no reciprocal causation, that is, that the causal variables are unaffected by the dependent variable. The problem is that the world may not have this causal structure.

Small-N comparison is therefore far more useful for assessing causal theories than conventional understandings of the 'comparative method' imply. Precisely because such research designs cover small numbers of cases, the researcher can investigate causal processes in each of them in detail, thereby assessing the relevant theories against especially diverse kinds of observations. Reconceptualized in these terms, the comparative method emerges not as a poor substitute for statistical analysis, but as a distinctive approach that offers a much richer set of observations, especially about causal processes, than statistical analyses normally allow."

### Re-thinking industrial policy

Deindustrialization is a global phenomenon taking place more rapidly in middle- income countries than in high-income ones. Despite the global decline of manufacturing employment, "industrial policy" is increasingly salient in research and policy debates. But deindustrialization poses significant challenges for industrial strategy—particularly as it relates to direct state investment in productive capacity.

In a new article, "Industrial Policy in the 21st Century," Ha-Joon Chang and Antonio Andreoni lay the groundwork for a new theory of industrial policy:

"Since the 18th century, the debate surrounding industrial policy has been one of the most important in the political economy of development. We discuss a number of issues which cannot be accommodated within the neoclassical framework and which are also often neglected by evolutionary and structuralist contributions—namely, commitment under uncertainty, learning in production, macroeconomic management, and conflict management. We also address three new challenges for industrial policy makers in a changing world: the global value chain, the increasing financialization of the world economy, and changes in the rules of the global economic system.

Despite differences across countries in terms of their stages and levels of industrialization, their macroeconomic regimes and their political economy settings, the three sets of neglected issues we focus on are and will remain of paramount importance. The need to address long-term grand challenges like climate change calls for massive and coordinated investments in energy systems, production practices and mobility. The achievement of these global transformations still depends on micro-level structural changes in productive organizations and government interventions in creating new worlds of production as well as managing industrial and social restructuring."

• "Industrial policy can no longer be about industry or manufacturing per se. As the world economy turns increasingly towards services, it is clear that we will need a conception of industrial policy that addresses the need to nurture and develop modern economic activities more broadly, including but not limited to manufacturing."

### Legal frameworks for sovereign debt restructuring

Despite contributing towards a series of crises (from the third world debt crisis of the 80s to the Euro-crisis of 2010), sovereign debt is rising across low-, middle-, and high-income economies, leading to renewed discussions around the macroeconomic consequences of sovereign debt restructuring and default.

In addition to debates about the economic consequences of default, a large academic and policy literature explores the varying legal architectures of debt contracts. In a 2002 paper, LEE BUCHHEIT and G. MITU GULATI present a history of contractual provisions for sovereign bonds in the United States, focusing specifically on the absence of collective action clauses, which are mandated in the UK.

From the article:

"In most contracts, the parties know each other's identity beforehand, and they make a conscious decision to enter into a legal relationship. In a multi-creditor debt instrument, the borrower's identity is of course known by each investor, but what the investors don't know is the identity of each other. When the bond issuer runs into financial difficulties, the actions of any one bondholder can dramatically affect the interests of all the other lenders.

Bonds issued by both corporate and sovereign borrowers in the early nineteenth century rarely contained provisions that contemplated collective decisionmaking by the bondholders. Each bond was a freestanding debt instrument; its terms could not be changed without the consent of its holder, and, if not paid when due, each holder was free to pursue her individual remedies against the issuer. The instruments did not require a holder to consult with, much less to act in concert with, fellow bondholders before, during or after a default. Although this approach ensured that each bondholder's claim against the borrower could not be deranged without that bondholder's consent, it also had the consequence of forcing financially-distressed corporate borrowers into bankruptcy (which in those days meant liquidation). This was, is, and ever shall be the "holdout creditor problem" in a debt workout.

One hundred years on, the financial community is again confronted with a remarkably similar problem. A sovereign bond issuer of the early twenty-first century is in much the same spot as the distressed corporate or railroad bond issuer of the early twentieth century. The merits of including majority action clauses in sovereign bonds as a method of neutralizing the holdout creditor are being proposed in some circles today, just as they were in the 1920s and 1930s in the context of corporate bonds. It may be feasible to engage the equity powers of U.S. federal courts in the oversight of some sovereign bond workouts with the result that the bondholders can be homogenized into a single voting class, and any court-approved compromise of the action will bind all members of that class."

• "By noticeably intensifying distributional conflict over scarce public resources, sovereign debt crises tend to lay bare underlying power dynamics that, during normal times, are quietly at work beneath the surface." Jerome Roos's recently published book uncovers the global distributional politics underlying the financialization of sovereign debt. Link. See also Barry Eichengreen's 2003 comparative overview of debt restructuring proposals. Link.

• "The Greek debt restructuring of 2012 stands out in the history of sovereign defaults. It achieved very large debt relief—over 50 per cent of 2012 GDP—with minimal financial disruption, but it did so at a cost."

### Policy feedback loops and US old-age policy

Researchers of policy history have long deliberated over explanatory frameworks: institutionalist accounts tend to focus on inherited conditions and path dependency in political development, while others stress the importance of social movements in shaping policy. Among the more dynamic analytical frameworks for the study of welfare politics is that of "policy feedbacks," which looks at the evolution of policy as an iterative process in which new policies change the conditions for further political engagement.

In a 2019 article, EDWIN AMENTA and THOMAS ALAN ELLIOTT look at the utility of these frameworks for explaining the character of old-age pensions in the US from the mid-1930s to 1950s.

Alexander Hertel-Fernandez is a political scientist who studies the mechanisms of influence. Focusing on the strategies of organized interests, including both business and labor, Hertel-Fernandez's helps illuminate crucial and poorly understood levers of American political economy. His 2019 book State Capture details the growing predominance of conservative lobbying groups at the state level across the country. His first book, Politics at Work, revealed the ways that employers actively shape the voting behaviors of their workers, shedding new light on the instruments of corporate power in American society. And his forthcoming book, Millionaires and Billionaires United, co-authored with Theda Skocpol and Vanessa Williamson, documents the growth of wealthy donor networks across the political spectrum.
