The effect of annual changes in automobile fuel economy standards

Since 1978 the Federal government has regulated the fuel economy of new cars sold in the United States. The purpose of Corporate Average Fuel Economy (CAFE) standards is to lessen the national dependence on foreign oil. Through the use of theoretical and empirical models this paper examines the impact of CAFE standards on the automobile industry and on energy consumption. It is shown that CAFE standards may or may not save energy. If CAFE does save energy, it does so at a prohibitive cost to the economy. CAFE standards are also shown to have a number of perverse impacts on the automobile industry as well as consumers.     

Does One Size Fit All? A currency union with asymmetric transmissions and a stability pact

The theory of optimal currency areas stresses that a single currency zone should have symmetry across shocks and structures. What happens if the monetary transmission mechanisms differ so that a common monetary policy has different effects in different places? Using a fully specified econometric model, we find that such asymmetries are likely to destabilise the business cycle and put countries out of phase with each other in a way that cannot be corrected by deficit-constrained national fiscal policies. Market discipline, however, could achieve this. Hence, the question is whether the markets would create sufficient discipline on their own.     

Assessing Preference Change on the US Supreme Court

The foundation upon which accounts of policy-motivated behaviorof Supreme Court justices are built consists of assumptionsabout the policy preferences of the justices. To date, mostscholars have assumed that the policy positions of Supreme Courtjustices remain consistent throughout the course of their careersand most measures of judicial ideology—such as Segal andCover scores—are time invariant. On its face, this assumptionis reasonable; Supreme Court justices serve with life tenureand are typically appointed after serving in other politicalor judicial roles. However, it is also possible that the worldviews,and thus the policy positions, of justices evolve through thecourse of their careers. In this article we use a Bayesian dynamicideal point model to investigate preference change on the USSupreme Court. The model allows for justices' ideal points tochange over time in a smooth fashion. We focus our attentionon the 16 justices who served for 10 or more terms and completedtheir service between the 1937 and 2003 terms. The results arestriking—14 of these 16 justices exhibit significant preferencechange. This has profound implications for the use of time-invariantpreference measures in applied work.     

Welfare Measurement and Measurement Error

The approximate effects of measurement error on a variety of measures of inequality and poverty are derived. They are shown to depend on the measurement error variance and functionals of the error–contaminated income distribution, but not on the form of the measurement error distribution, and to be accurate within a rich class of error–free income distributions and measurement error distributions. The functionals of the error–contaminated income distribution that approximate the measurement error induced distortions can be estimated. So it is possible to investigate the sensitivity of welfare measures to alternative amounts of measurement error and, when an estimate of the measurement error variance is available, to calculate corrected welfare measures. The methods are illustrated in an application using Indonesian household expenditure data.     

Using Micro Data to Test the Divergence between Prices and Labour Values

An extremely robust finding in Marxian empirical economics is the 'Shaikh result' that estimates of labour values are closely correlated with prices. This result is established using input-output data together with a standard procedure in which variations in money wages are assumed to reflect labour quality. Two problems with this standard procedure can be identified. First, there is no translation between money units of wages and labour value units of output produced by different types of heterogeneous labour. Second, the standard procedure assumes perfectly competitive labour markets. In this paper, a new micro procedure for estimating labour values is developed in which both of these problems are addressed. To translate between money wage rates and the labour value of outputs a practical starting point for empirical analysis is suggested using some of the readily available tools of neoclassical economics. The assumption of perfect competition is accordingly relaxed by estimating a microeconometric wage equation using data from the UK Family Expenditure Survey. Conjoining this micro data with input-output data, estimates of labour values are used to test the Shaikh result, which is found not to hold in this particular exercise; with labour values diverging substantially from money prices.     

Portfolio Capital Flows: Hot or Cold?

A distinction is often made between short-term and long-termcapital flows: the former are deemed unstable hot money andthe latter are deemed stable cold money. Using time-series analysisof balance of payments data for five industrial and five developingcountries, we find that in most cases the labels "short-term"and "long-term" do not provide any information about the time-seriesproperties of the flow. In particular, long-term flows are oftenas volatile as short-term flows, and the time it takes for anunexpected shock to a flow to die out is similar across flows.long-term flows are also at least as unpredictable as short-termflows, and knowledge of the type of flow does not improve theability to forecast the aggregate capital account.

An analysis of repressed inflation in two transition economies

We construct a simple model that tests for repressed inflation by estimating a true rate of inflation that explains behavior of observed money demand. We estimate the model using quarterly data for Czechoslovakia and Poland. Although our results should be viewed as preliminary, given the imperfect nature of our data, we do have strong evidence that, prior to 1991, there was considerable repressed inflation in Poland, while there was essentially no repressed inflation in Czechoslovakia.This paper was funded by a World Bank project on formerly planned economies. We would like to thank Jong-goo Park for suggesting the topic, and Fabrizio Coricelli and Adnan Mazarei for helpful discussions. The views expressed here are our own and do not necessarily reflect the opinions of the World Bank.     

Capitalization versus Expensing: Evidence on the Uncertainty of Future Earnings from Capital Expenditures versus R&D Outlays

We propose and implement a new method to estimate the relation between R&D investments and the uncertainty of future benefits from those investments. The empirical analysis compares the relative contributions of current investments in R&D and PP&E to future earnings variability using a sample of roughly 50,000 firm-year observations from 1972–1997. Evidence is strongly consistent with the hypothesis that R&D investments generate future benefits that are far more uncertain than benefits from investments in PP&E. Our results should help the current discussion on accounting for R&D and the methodology might be helpful in standard setting in other contexts as well.
