Abstract:
Understanding commodity prices dynamics is of crucial importance for assessing the persistence of cost-push costs or for countries dependent on commodity exports. Unfortunately, despite decades of research, the workhorse theoretical model in the field, the rational expectations storage model, is yet to be empirically validated. This paper provides the first full empirical test of the storage model. We first build a new storage model featuring a supply response, long-run demand and cost trends, and four structural shocks. We then develop a flexible empirical approach which relies on the indirect inference method and exploits the joint dynamics of prices and quantities unlike previous estimations which only use price information. The information contained in quantities is essential to relax restrictive identifying assumptions and empirically assess the overall consistency of the model's new features. Finally, we carry out a structural estimation on the aggregate index of the world most important staple food products: maize, rice, soybeans, and wheat. The results show that our extended storage model is consistent with most of the moments in the data, including the high price autocorrelation of which up to 42% can be explained by the transfer of inventories over time. They also show that, although for these commodities supply shocks are the main drivers of market dynamics, over the past 60 years all price spikes have been associated with large positive demand shocks.

2. World Interest Rates and Macroeconomic Adjustments in Developing Commodity Producing Countries

Abstract:
With commodities becoming international financial securities, commodity prices are affected by the international financial cycle. With this evidence in mind, this paper reconsiders the macroeconomic adjustment of developing commodity-exporting countries to changes in world interest rates. We proceed by building a model of a small open economy that produces a non-tradable good and a storable tradable commodity. The difference with standard models of small open economies lies in the endogenous response of commodity prices which -due to commodity storage- adjust to variations in international interest rates. We find that the endogenous response of commodity prices amplifies the reaction of commodity exporting countries to international monetary shocks. This suggests that commodity exporting countries are more vulnerable to unfavourable international monetary disturbances than other small open economies. In particular, because of the existence of the commodity price channel, even those small open commodity-exporting economies that are disconnected from international financial markets can be affected by the international financial cycle.

Abstract:
We extend Lucas’s classic asset-price model by opening the stochastic process driving dividends to Knightian uncertainty arising from unforeseeable change. Implementing Muth’s hypothesis, we represent participants’ expectations as being consistent with our model’s predictions and formalize their ambiguity- averse decisions with maximization of intertemporal multiple-priors utility. We characterize the asset-price function with a stochastic Euler equation and derive a novel prediction that the relationship between prices and dividends undergoes unforeseeable change. Our approach accords participants’ expectations, driven by both fundamental and psychological factors, an autonomous role in driving the asset price over time, without presuming that participants are irrational.

Abstract:
This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent rendering standard approaches inapplicable. Instead, we require observation of profits or other optimizing-values such as costs or revenues, and either prices or price proxies of flexibly chosen variables. We extend classical duality results for price-taking firms to a setup with discrete heterogeneity, endogeneity, and limited variation in possibly latent prices. Finally, we show that convergence results for nonparametric estimators may be directly converted to convergence results for production sets.

Abstract:
This paper studies the multidimensional nature of investments in children within a dynamic framework. In particular, we examine the roles of parental time investments, purchased home goods/services inputs, and market-based child care services. We first document strong increases in total investment expenditures by maternal education; yet expenditure shares, which skew heavily towards parental time, vary little with parental schooling. Second, we develop an intergenerational lifecycle model with multiple child investment inputs to study these patterns and the impacts of policies that alter the prices of different inputs. We analytically characterize investment behavior, focusing on the substitutability of different investment inputs and the way parental skills affect the productivity of family-based inputs. Third, we develop an estimation strategy that exploits intratemporal optimality conditions based on relative demand to estimate substitutability between inputs, the relative productivity of different inputs, and the role played by parental education. This approach requires no assumptions about the dynamics of skill investment, preferences, or credit markets. We also account for mismeasured inputs and wages, as well as unobserved heterogeneity in parenting skills. We further show how noisy measures of child achievement (measured several years apart) can also be incorporated in a generalized method of moments approach to additionally identify the dynamics of skill accumulation. Fourth, we use data from the Child Development Supplement of the Panel Study of Income Dynamics to estimate the skill production technology for children ages 12 and younger. Our estimates suggest complementarity between parental time and home goods/services inputs as well as between these family-based inputs and market-based child care, with elasticities of substitution ranging from 0.2 to 0.5. We find no systematic effects of parental education on the relative productivity of parental time and other home inputs. Finally, we use counterfactual simulations to explore the extent and sources of variation in investments across families, as well as investment responses to changes in input prices. We find that variation in prices explains 48% of the overall variance in investment expenditures, and differences in wages explain more than half of the investment expenditure gap between college-educated and non-college-educated parents. We further show that accounting for the degree of input complementarity implied by our estimates has important implications for the responses of individual inputs to any price change and for the responses in total investments and skill accumulation to large (but not small) price changes.

Abstract:
This paper describes the new CEPII-MULTIPRIL database on Multilateral Price Levels (MPL) introduced in 2020. The MULTIPRIL database covers a wide sample of 178 countries over the 1990-2018 period, and includes relative price level series computed vis-à-vis two sets of trading partners (177 and the top 30) according to three different trade-weighting schemes. It also contains MPL-based currency misalignments series for 156 countries over the 1991-2018 period. MULTIPRIL offers the potential to improve the coverage and quality of worldwide price-competitiveness comparisons. By focusing on price level data, it usefully complements the EQCHANGE database on equilibrium exchange rates and currency misalignments derived from series in indices. Its multilateral setting provides a more comprehensive picture of relative price levels and currency misalignments compared to existing bilateral measures.

8. Imperfect competition in product and labour markets. A quantitative analysis

Abstract:
We disentangle the extent of imperfect competition in product and labor markets using plant level data. We derive a formula for the ratio between markups and markdowns assuming costminimizing firms that face upward-sloping labour supply and downward-sloping product demand curves. We then separate this combined measure of market power by estimating firm-level labour supply elasticities instrumenting wages with a different set of instruments: including the use of intermediate inputs, input price shocks, and TFP shocks. Our results suggest that both markets exhibit imperfect competition, but the variation is mainly driven by markups. We also estimate the relative gains of removing market power dispersion on allocative efficiency, finding that markups are more important on TFP than markdowns.

9. In Defense of Alternatives to Pollution Pricing

Abstract:
2020 marks the 100th anniversary of the publication of economist Arthur Cecil Pigou’s The Economics of Welfare. This book is widely recognized as introducing the concept of Pigouvian welfare economics, that is, of using the basic tools of neoclassical economics to study how to improve the functioning of the economy and people’s lives. While Pigou’s analysis touched on many topics in the economy, the part of Pigouvian welfare economics most remembered today by environmental economists (and perhaps by anyone who has taken an introductory microeconomics course) is his theory of externalities. Pigou argued that externalities, like pollution or congestion, create market failures, but that they can be cost-effectively remedied using taxes or subsidies. These price policies have come to be known as Pigouvian pricing, or Pigouvian taxes or subsidies. If there is one common lesson argued by most environmental economists today regarding the design of environmental policy, it is: the best way to correct the market failure caused by pollution is Pigouvian pricing. According to this argument, a price should be levied on pollution equal to the value of the damages it causes to society. The price can be directly applied via a pollution tax, or indirectly via a cap-and-trade system where the permit price becomes the Pigouvian price on pollution. If the price is correct, then the most efficient outcome will be realized, and it will be achieved at the lowest possible cost to society. A corollary is that environmental policies other than price policies, for example technology mandates or performance standards (what economists often call “command-and-control” policies), are inferior and should not be used.

10. Can Transparency Lower Prices and Improve Access to Pharmaceuticals? It Depends

Abstract:
spending on pharmaceuticals and other healthcare commodities is high and makes up a large proportion of healthcare spending in rich and poorer markets alike. A popular response to the problem of escalating drugs budgets has been transparency of drug pricing within and across borders. In a rare alignment of policy priorities, the Trump administration, the US Senate, and the World Health Organisation are calling for more transparency of the prices paid for prescription drugs as a means of tackling the ever-growing pharmaceuticals bill. Recently Italy’s health minister joined in, calling for a World Health Assembly resolution which would mandate WHO to “provide governments with a forum for sharing information on drug prices, revenues, research and development costs, public sector investments and research and development subsidies, marketing costs and other related information.” But is price transparency really the answer to healthcare systems’ fiscal sustainability challenges as they strive to expand access to new technologies or even merely sustain provision within strained public budgets? Well, it depends!
