Knowledge that Transforms

This paper provides a simple and empirically plausible model of artworks as investment vehicles. It reconciles the observation that average financial returns for collectibles are low and volatile with the theory of consumption-based asset pricing. Art assets are appealing both for their ability to transfer consumption over time and for their use as signals of wealth, as in the literature on the demand for luxuries. Adding art value to utility, returns also reflect this “conspicuous consumption” dividend; as a result, average financial returns are low. Risk premia for artworks are predicted to be modest or even negative.

We study peer effects in the workplace. Specifically, we investigate whether, how, and why the productivity of a worker depends on the productivity of coworkers in the same team. Using high-frequency data on worker productivity from a large supermarket chain, we find strong evidence of positive productivity spillovers from the introduction of highly productive personnel into a shift. Worker effort is positively related to the productivity of workers who see him, but not workers who do not see him. Additionally, workers respond more to the presence of coworkers with whom they frequently interact. We conclude that social pressure can partially internalize free-riding externalities that are built into many workplaces.

Many classes of assets are illiquid or nonmarketable in that they cannot always be traded immediately. Thus, a portfolio position in these becomes at least temporarily irreversible. We study the asset-pricing implications of this type of illiquidity in an exchange economy with heterogeneous agents. In this market, one asset is always liquid. The other asset can be traded initially, but then not again until after a “blackout” period. Illiquidity has a dramatic effect. Agents abandon diversification and choose polarized portfolios instead. The value of liquidity can represent a large portion of the equilibrium price of an asset.

The article discusses and analyzes data from several economic experiments in a household survey with mothers of preschool children. The researchers measured competitiveness by giving the subjects the choice between competing in a tournament or receiving a piece rate for a real effort task. The subjects also participated in lottery choices, which enabled the researchers to assess their risk preferences. The relationship between social preferences and competitiveness in the sample of mothers of preschool children was analyzed. The hypothesis that egalitarian subjects aren't as likely to self-select into competitive environments, which can produce winners and losers, was tested. A negative relationship between egalitarian choices and self-selection into competition was found.

We use a new firm-level dataset that establishes the location, ownership, and activity of 650,000 multinational subsidiaries. Using a combination of four-digit-level information and input-output tables, we find the share of vertical FDI (subsidiaries that provide inputs to their parent firms) to be larger than commonly thought, even within developed countries. Most subsidiaries are not readily explained by the comparative advantage considerations whereby multinationals locate activities abroad to take advantage of factor cost differences. Instead, multinationals tend to own the stages of production proximate to their final production, giving rise to a class of high-skill, intra-industry vertical FDI.

Pollution emitted by US manufacturers declined markedly over the past several decades, even as real manufacturing output increased. I first show that most of the decline in US manufacturing pollution has resulted from changing production processes (“technology”), rather than changes in the mix of goods produced. I then show that increased net imports of polluting goods (“international trade”) accounts for only a small portion of the pollution reductions from the changing mix of goods. Together, these two findings demonstrate that shifting polluting industries overseas explains only a minor part—less than 10 percent—of the cleanup of US manufacturing.

Heterogeneity is ubiquitous in firm-level and sectoral data. Equilibrium models, how-ever, typically assume a representative firm, as in Andrew B. Abel and Olivier J. Blanchard (1983). The representative firm paradigm leaves no role for the distribution of capital. We model capital reallocation in a general equilibrium model with two sectors. Capital adjustment costs capture illiquidity in our model, similar to Hirofumi Uzawa’s (1969) capital installation technology. We follow Fumio Hayashi (1982) in assuming that the production technology is linearly homogeneous, which allows us to focus on the sectoral distribution of capital, separately from the level of total capital. The two sectors may have different levels of productivity, and we show that the distribution of capital between the two sectors is the single state variable gov-erning investment, growth, and valuation in the economy.We analytically characterize prices and quan-tities, including investment, growth, the interest rate, and the price of capital (Tobin’s

Building on prior literature that constrained individuals consume the most out of a tax rebate, we study the tradeoffs high interest borrowers face when they received their 2008 tax stimulus checks. We find a persistent decline in payday borrowing in the pay cycles that follow the receipt of the tax rebate. The reduction in borrowing is a significant fraction of the mean outstanding loan (12%) and appears fairly persistent over the time, but is moderate in dollar magnitude (about $35) relative to the size of the rebate check ($600 per person). In trying to reconcile this finding with the cost of not retiring expensive payday debt, we find substantial heterogeneity across borrowers. Among individuals that we classify as temptation spenders (e.g. those that use 400 % APR loans to buy electronic goods or go on vacation), we find no reduction in payday borrowing after the tax rebate is issued, but this group represents only a small fraction of payday borrowers. A second group for which we find no debt retirement post-check is the set of borrowers that appear to use what should be short-term payday loans as a long-term financing solution. We infer that the marginal use of the tax rebate for this group was to deal with regular

In mid-1995, a government effort to reduce the supply of methamphetamine precursors successfully disrupted the methamphetamine market and interrupted a trajectory of increasing usage. The price of methamphetamine tripled and purity declined from 90 percent to 20 percent. Simultaneously, amphetaminerelated hospital and treatment admissions dropped 50 percent and 35 percent, respectively. Methamphetamine use among arrestees declined 55 percent. Although felony methamphetamine arrests fell 50 percent, there is no evidence of substantial reductions in property or violent crime. The impact was largely temporary. The price returned to its original level within four months; purity, hospital admissions, treatment admissions, and arrests approached preintervention levels within eighteen months.
