The Unassuming Economist

My work with Davide Furceri, and Jonathan D. Ostry on The aggregate and disttributional effects of financial globalization: evidence from macro and sectoral data makes into the list of the research that shaped our world in 2017–put together by Dan Kopf of Quartz.

The aggregate and disttributional effects of financial globalization: evidence from macro and sectoral data (pdf) by Davide Furceri, Prakash Loungani and Jonathan D. Ostry

Main finding: Foreign finance has led to more inequality.

Nominating economist: Dani Rodrik, Harvard University

Specialization: Globalization and economic development

Why? “In brief, opening up to foreign finance (“financial globalization”) produces limited gains to aggregate output while generating significant increases in income inequality (a higher share of top incomes, a lower labor share, etc.). This paper’s conclusions are significant as the authors are researchers at the International Monetary Fund, which aggressively pushed for financial globalization until recently.”

From Dani Rodrik’s weblog:

Ten commandments for economists

1. Economics is a collection of models; cherish their diversity.

2. It’s a model, not the model.

3. Make your model simple enough to isolate specific causes and how they work, but not so simple that it leaves out key interactions among causes.

4. Unrealistic assumptions are OK; unrealistic critical assumptions are not OK.

5. The world is (almost) always second-best.

6. To map a model to the real world you need explicit empirical diagnostics, which is more craft than science.

7. Do not confuse agreement among economists for certainty about how the world works.

8. It’s OK to say “I don’t know” when asked about the economy or policy.

9. Efficiency is not everything.

10. Substituting your values for the public’s is an abuse of your expertise.

Ten commandments for non-economists

1. Economics is a collection of models with no predetermined conclusions; reject any arguments otherwise.

2. Do not criticize an economist’s model because of its assumptions; ask how the results would change if certain problematic assumptions were more realistic.

3. Analysis requires simplicity; beware of incoherence that passes itself off as complexity.

4. Do not let math scare you; economists use math not because they are smart, but because they are not smart enough.

5. When an economist makes a recommendation, ask what makes him/her sure the underlying model applies to the case at hand.

6. When an economist uses the term “economic welfare,” ask what s/he means by it.

7. Beware that an economist may speak differently in public than in the seminar room.

8. Economists don’t (all) worship markets, but they know better how they work than you do.

9. If you think all economists think alike, attend one of their seminars.

10. If you think economists are especially rude to non-economists, attend one of their seminars.

From VoxEU: “The Eurozone crisis has opened fault lines between German economists and policymakers and those in a number of Eurozone (in particular periphery) countries.This column introduces a new eBook explaining the historical development of the ordoliberal school of economics and its influence on German policymaking, and contrasting it critically with what we like to call the Anglo-Saxon-Latin pragmatism of economic policymaking.”

Dani Rodrik says:

“That neoliberalism is a slippery, shifting concept, with no explicit lobby of defenders, does not mean that it is irrelevant or unreal. Who can deny that the world has experienced a decisive shift toward markets from the 1980s on? Or that center-left politicians—Democrats in the United States, Socialists and Social Democrats in Europe—enthusiastically adopted some of the central creeds of Thatcherism and Reaganism, such as deregulation, privatization, financial liberalization, and individual enterprise? Much of our contemporary policy discussion remains infused with norms and principles supposedly grounded in homo economicus.

But the looseness of the term neoliberalism also means that criticism of it often misses the mark. There is nothing wrong with markets, private entrepreneurship, or incentives—when deployed appropriately. Their creative use lies behind the most significant economic achievements of our time. As we heap scorn on neoliberalism, we risk throwing out some of neoliberalism’s useful ideas.

The real trouble is that mainstream economics shades too easily into ideology, constraining the choices that we appear to have and providing cookie-cutter solutions. A proper understanding of the economics that lies behind neoliberalism would allow us to identify—and to reject—ideology when it masquerades as economic science. Most importantly it would help us develop the institutional imagination we badly need to redesign capitalism for the twenty-first century.”

My paper with Sangyup Choi, Davide Furceri, and Yi Huang on the effects of effect of aggregate uncertainty shocks on sectoral productivity is now forthcoming in the Journal of International Money and Finance and is available (link) at the JIMF website. First, we find that an increase in aggregate uncertainty reduces productivity growth more in industries that depend heavily on external finance. Second, the mechanism at play is that during periods of high uncertainty, firms that are credit constrained switch the composition of investment by reducing productivity-enhancing investment that is more subject to liquidity risks. Third, the mechanism is stronger during recessions, when credit constraints bind more. For those without access to JIMF, an earlier working paper (link) version is available.
