Abstract:
With the goal of driving down drug costs, governments across the globe have instituted various forms of pharmaceutical price control policies. Understanding the impacts of such policies is particularly important in low- and middle-income countries, where lack of insurance coverage means that prices can serve as a barrier to access for patients. In this paper, we examine the theoretical and empirical effects of one implementation of pharmaceutical price controls, in which the Indian government placed price ceilings on a set of essential medicines. We find that the legislation resulted in broadly declining prices amongst both directly impacted products and competing products. However, the legislation also led to decreased sales of price-controlled and closely related products, preventing trade that would have otherwise occurred. The sales of small, local generics manufacturers were most impacted by the legislation, seeing a 14.5 percent decrease in market share and a 5.3 percent decrease in sales. These products tend to be inexpensive, but we use novel data to show that they are also of lower average quality. We provide evidence that the legislation impacted consumer types differentially. The benefits of the legislation were largest for quality-sensitive consumers, while the downsides largely affected poor and rural consumers, two groups already suffering from low access to medicines.

22. Approaches to Price Formation in Financialised Commodity Markets

Working Paper

School of Oriental and African Studies - University of London
Abstract:
A recent debate over the financialisation of commodity markets has stimulated the development of approaches to price formation which incorporate index traders as a new trader category in commodity futures markets. I survey these new approaches by retracing their emergence to traditional price formation models and show that these new models arise from a synthesis between commodity arbitrage pricing and asset pricing theories in the tradition of Keynesian inspired hedging pressure models. Based on these insights, I derive testable hypotheses to provide guidance for a growing literature that seeks to empirically evaluate the effects of index traders on price discovery and risk management in commodity futures markets.

23. Price Discovery in Commodity Futures and Cash Markets with Heterogenous Agents

Author:
Sophie van Huellen
Publication Date:

Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
The paper develops a price discovery model for commodity futures markets that accounts for two forms of limits to arbitrage caused by transaction costs and noise trader risk. Four market regimes are identified: (1) effective arbitrage, (2) transaction costs but no noise trader risk, (3) no transaction costs but noise trader risk and (4) both transaction costs and noise trader risk. It is shown that commodity prices are driven by both market fundamentals and speculative trader positions under the latter two regimes. Further, speculative effects spill over to the cash market under regime (3) but are confined to the futures market under regime (4). The model is empirically tested using data from six grain and soft commodity markets. While regime (4) is rare and short lived, regime (3) with some noise trader risk and varying elasticity of arbitrage prevails

24. Emissions Trading in the Presence of Price-Regulated Polluting Firms: How Costly Are Free Allowances?

Author:
Bruno Lanz and Sebastian Rausch
Publication Date:

Content Type:
Working Paper
Institution:
Centre for International Environmental Studies, The Graduate Institute (IHEID)
Abstract:
We study whether to auction or to freely distribute emissions allowances when some firms participating in emissions trading are subject to price regulation. We show that free allowances allocated to price-regulated firms effectively act as a subsidy to output, distort consumer choices, and generally induce higher output and emissions by price-regulated firms. This provides a cost-effectiveness argument for an auction-based allocation of allowances (or equivalently an emissions tax). For real-world economies such as the Unites States, in which about 20 percent of total carbon dioxide emissions are generated by price-regulated electricity producers, our quantitative analysis suggests that free allowances increase economy-wide welfare costs of the policy by 40-80 percent relative to an auction. Given large disparities in regional welfare impacts, we show that the inefficiencies are mainly driven by the emissions intensity of electricity producers in regions with a high degree of price regulation.

25. Do places of worship affect housing prices? Evidence from Germany

Author:

Working Paper
Institution:

Abstract:
Using hedonic pricing models, this paper analyzes the impact of places of worship on the prices of adjacent condominiums in Hamburg, Germany. This is the first study on this subject to have been conducted outside the United States. It is also the first work to examine the externalities of places of worship of all five world religions. Furthermore, it is the first study that analyzes the effect of bell ringing on the adjacent residential property prices. Controlling for spatial dependence and by using potentiality variables positive externalities of places of worship within a radius of 1,000m were identified. Compared to properties beyond this threshold, price premiums of 4.8% were detected for condominiums at distances of 100m to 200m to the next place of worship. The results also show that the positive externalities near mosques do not differ from those of places of worship of other religions and that the positive effect of churches continues to be felt even after they have been deconsecrated. The influence of church bell ringing on the prices of surrounding residential properties, however, could not be substantiated.

26. Missing Import Price Changes and Low Exchange Rate Pass-Through

Abstract:
A large body of empirical work has found that exchange rate movements have only modest effects on inflation. However, the response of an import price index to exchange rate movements may be underestimated because some import price changes are missed when constructing the index. We investigate downward biases that arise when items experiencing a price change are especially likely to exit or to enter the index. We show that, in theoretical pricing models, entry and exit have different implications for the timing and size of these biases. Using Bureau of Labor Statistics (BLS) microdata, we derive empirical bounds on the magnitude of these biases and construct alternative price indexes that are less subject to selection effects. Our analysis suggests that the biases induced by selective exits and entries are modest over typical forecast horizons. As such, the empirical evidence continues to support the conclusion that exchange rate pass-through to U.S. import prices is low.

27. Do Oil Prices Help Forecast U.S. Real GDP? The Role of Nonlinearities and Asymmetries

Abstract:
There is a long tradition of using oil prices to forecast U.S. real GDP. It has been suggested that the predictive relationship between the price of oil and one-quarter ahead U.S. real GDP is nonlinear in that (1) oil price increases matter only to the extent that they exceed the maximum oil price in recent years and that (2) oil price decreases do not matter at all. We examine, first, whether the evidence of in-sample predictability in support of this view extends to out-of-sample forecasts. Second, we discuss how to extend this forecasting approach to higher horizons. Third, we compare the resulting class of nonlinear models to alternative economically plausible nonlinear specifications and examine which aspect of the model is most useful for forecasting. We show that the asymmetry embodied in commonly used nonlinear transformations of the price of oil is not helpful for out-of-sample forecasting; more robust and more accurate real GDP forecasts are obtained from symmetric nonlinear models based on the three-year net oil price change. Finally, we quantify the extent to which the 2008 recession could have been forecast using the latter class of time-varying threshold models.

28. Individual Price Adjustment Along the Extensive Margin

Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
Firms employ a rich variety of pricing strategies whose implications for aggregate price dynamics often diverge. This situation poses a challenge for macroeconomists interested in bridging micro and macro price stickiness. In responding to this challenge, we note that differences in macro price stickiness across pricing mechanisms can often be traced back to price changes that are either triggered or cancelled by shocks. We exploit observed micro price behavior to quantify the importance of this margin of adjustment for the response of inflation to shocks. Across a range of empirical exercises, we find strong evidence that changes in the timing of price adjustments contribute significantly to the flexibility of the aggregate price level.

30. Commodity Price Movements in a General Equilibrium Model of Storage

Abstract:
We embed the canonical rational expectations competitive storage model into a general equilibrium framework thereby allowing the non-linear commodity price dynamics implied by the competitive storage model to interact with the broader macroeconomy. Our main result is that the endogenous movement in interest rates implied under general equilibrium enhances the effects of competitive storage on commodity prices. Compared to a model in which the real interest rate is fixed, we find that storage in general equilibrium leads to more persistence in commodity prices and somewhat lower volatility. Moreover, the frequency of stockouts is lower in general equilibrium. A key mechanism driving this result is a link between the ability of the household to smooth consumption over time and the level of storage in the stochasic equilibrium. Finally, the model is used to examine the macroeconomic effects of both biofuel subsidies for ethanol producers and, separately, subsidies designed to insulate households from high food prices.
