We study the evolution of belief systems that suppress productive effort. These include concerns about the envy of others, beliefs in the importance of luck for success, disdain for competitive effort, and traditional beliefs in witchcraft. We show that such demotivating beliefs can evolve when...

We estimate long-run elasticities of substitution between intermediate inputs for Indian manufacturing plants. India's trade liberalization in the early 1990s provides an ideal natural policy experiment, with permanent and heterogeneous tariff reductions inducing changes in relative prices which...

This article provides an overview of the literature on mobility in developing countries. Explicit distinctions are drawn between directional and non-directional measures, absolute and relative measures, and combinations thereof. We note that the scarcity of panel data has hindered the...

We study sovereign external debt crises over the past 200 years, with a focus on creditor losses, or "haircuts". Our sample covers 327 sovereign debt restructurings with external private creditors over 205 default spells since 1815. Creditor losses vary widely (from none to 100%), but the...

Do periods of persistently loose monetary policy increase financial fragility and the likelihood of a financial crisis? This is a central question for policymakers, yet the literature does not provide systematic empirical evidence about this link at the aggregate level. In this paper we fill...

This paper surveys the recent empirical literature on historical banking crises, defined as events taking place before 1980. Advances in data collection and identification have provided new insights into the causes and consequences of crises both immediately and over the long run. We highlight...

We introduce a new database of historical Genuine Savings (GS), an indicator of sustainable development promoted by the World Bank and widely used in contemporary economic research. GS derives from the theoretical work on wealth accounting, and addresses shortcomings in conventional metrics of...

We consider the debut of a new monetary instrument, central bank digital currencies (CBDCs). Drawing on examples from monetary history, we argue that a successful monetary transformation must combine microeconomic efficiency with macroeconomic credibility. A paradoxical feature of these...

We investigate the origins and implications of zero-sum thinking - the belief that gains for one individual or group tend to come at the cost of others. Using a new survey of a representative sample of 20,400 US residents, we measure zero-sum thinking, political preferences, policy views, and a...

We discuss recent work evaluating the role of the government in shaping the economy during the long 19th century, a practice we refer to as industrial policy. We show that states deployed a vast variety of different policies aimed at, primarily, but not exclusively, fostering industrialization....
