Knowledge that Transforms

This paper seeks to understand the drivers of country-level multi-factor productivity (MFP) with a special emphasis on product and labour market policies and the quality of institutions. For a panel of OECD countries, we find that anticompetitive product market regulations reduce MFP levels and that higher innovation intensity and greater openness result in higher MFP. We also find that the impact of product market regulations on MFP may depend on the level of labour market regulations. Better institutions, a more business friendly environment and lower barriers to trade and investment amplify the positive impact of R&D spending on MFP. Finally, we also show that cross-country MFP variations can be explained to a considerable extent by cross-country variation in labour market regulations, barriers to trade and investment and institutions.

We provide a systematic empirical study of the diffusion and adoption patterns of data-driven decision making (DDD) in the U.S. Using data collected by the Census Bureau for a large representative sample of manufacturing plants, we find that DDD rates nearly tripled (11%-30%) between 2005 and 2010. This rapid diffusion, along with results from a companion paper, are consistent with case-based evidence that DDD tends to be productivity-enhancing. Yet certain plants are significantly more likely to adopt than others. Key correlates of adoption are size, presence of potential complements such as information technology and educated workers, and firm learning.

We investigate the role of macroprudential policies in mitigating liquidity traps. When constrained households engage in deleveraging, the interest rate needs to fall to induce unconstrained households to pick up the decline in aggregate demand. If the fall in the interest rate is limited by the zero lower bound, aggregate demand is insufficient and the economy enters a liquidity trap. In this environment, households' ex ante leverage and insurance decisions are associated with aggregate demand externalities. Welfare can be improved with macroprudential policies targeted toward reducing leverage. Interest rate policy is inferior to macroprudential policies in dealing with excessive leverage.

We endogenize entry to a security-bid auction, where participation is costly and bidders must decide given their private valuations whether to participate. We first consider any minimum reserve security-bid of a fixed expected value that weakly exceeds the asset's value when retained by the seller. DeMarzo, Kremer, and Skrzypacz (2005) establish that with a fixed number of bidders, auctions with steeper securities yield the seller more revenues. Counterintuitively, we find that auctions with steeper securities also attract more entry, further enhancing the revenues from such auctions. We then establish that with optimal reserve securities, auctions with steeper securities always yield higher expected revenues.

Using data collected by Forbes since the 1990s, I examine the emergence and survival of the super-wealthy in Russia over the past two decades and compare Russia's record to those of other countries. The major surge in the number of Russian billionaires came in the mid-2000s, mirroring the dynamic worldwide. While early billionaires were predominantly found in the oil, gas, metals, and banking sectors, the distribution has become more diverse, now including some in trade, real estate, chemicals, and information technology. Only a minority of today's Russian billionaires acquired significant assets in the privatization of the 1990s.

The surge in credit and house prices that preceded the Great Recession was particularly pronounced in ZIP codes with a higher fraction of subprime borrowers We present a simple model with prime and subprime borrowers distributed across geographic locations, which can reproduce this stylized fact as a result of an expansion in the supply of credit. Due to their low income, subprime households are constrained in their ability to meet interest payments and hence sustain debt. As a result, when the supply of credit increases and interest rates fall, they take on disproportionately more debt than their prime counterparts, who are not subject to that constraint.

Value-added (VA) models measure agents' productivity based on the outcomes they produce. The utility of VA models for performance evaluation depends on the extent to which VA estimates are biased by selection. One common method of evaluating bias in VA is to test for balance in lagged values of the outcome. We show that such balance tests do not yield robust information about bias in value-added models using Monte Carlo simulations. Even unbiased VA estimates can be correlated with lagged outcomes. More generally, tests using lagged outcomes are uninformative about the degree of bias in misspecified VA models. The source of these results is that VA is itself estimated using historical data, leading to non-transparent correlations between VA and lagged outcomes.

We propose a parsimonious model of bilateral trade under asymmetric information to shed light on the prevalence of intermediation chains that stand between buyers and sellers in many decentralized markets. Our model features a classic problem in economics where an agent uses his market power to inefficiently screen a privately informed counterparty. Paradoxically, involving moderately informed intermediaries also endowed with market power can improve trade efficiency. Long intermediation chains in which each trader's information set is similar to those of his direct counterparties limit traders' incentives to post prices that reduce trade volume and jeopardize gains to trade.

This paper shows that an income effect can drive expenditure switching between domestic and imported goods. We use a unique Latvian scanner-level dataset, covering the 2008–2009 crisis, to document several empirical findings. First, expenditure switching accounted for one-third of the fall in imports, and took place within narrowly defined product groups. Second, there was no corresponding within-group change in relative prices. Third, consumers substituted from expensive imports to cheaper domestic alternatives. These findings motivate us to estimate a model of nonhomothetic consumer demand, which explains two-thirds of the observed expenditure switching. Estimated switching is driven by income, not changes in relative prices.

We build an economico-epidemiological Solow-Swan model. Mortality and morbidity effects on effective labor are taken into account. A Ben-Porath-like mechanism affects the dynamics of the saving rate and reduces labor productivity. Based on optimal projections of the demographic and economic South African series on the period 2000-2050, we identify a delayed effect of HIV/AIDS on economic growth: the growth rate gap between the AIDS and no-AIDS scenarios is rather stable between 2010 and 2020, but then it increases sharply between 2020 and 2030, keeps increasing at a much lower pace between 2030 and 2040, and finally stabilizes after 2040. The fall in active population is the main factor behind AIDS impact on economic growth during the decade 2020-2030 while the Ben-Porath mechanism on labor productivity is more relevant in the last decade. Physical capital accumulation plays a minor role.
