Politically influenced counterterrorism policy and welfare efficiency

The paper examines how two targeted countries strategically deploy their counterterror forces when lobbying defense firms influence counterterror provision. For proactive measures, lobbying activities in a single targeted country lessen underprovision, raise overall counterterrorism, and reduce terrorism. Welfare decreases in the lobbied country but increases in the other targeted country owing to enhanced free riding. Lobbying influence on the targeted countries' welfare is tied to terrorists' targeting preferences and how the lobbied government weighs citizens’ welfare. Lobbying in both targeted countries may result in the first-best equilibrium. International policy coordination may lead to less efficient outcomes than the noncooperative equilibrium.     

International flows of people and institutional change

International travel clearly increases human interaction over space and exposes societies to foreign influences, foreign ideas, and foreign institutions. Does international travel promote institutional change in a traveler's home country? This paper uses panel data from 149 countries to test the hypothesis of institutional change stemming from international travel. We generally find that foreign travel does not affect political institutions. In one sub-sample, we find limited evidence that international travel can be a determinant of institutional quality in the home country depending upon whether the home country is an autocracy or democracy.     

Life Cycle Price Trends and Product Replacement: Implications for the Measurement of Inflation

The paper explores the extent to which products follow systematic pricing patterns over their life cycle and the impact this has on the measurement of inflation. Using a large U.S. scanner data set on supermarket products and applying flexible regression methods, we find that on average prices decline as items age. This life cycle price change is often attributed to quality difference in the construction of CPI as items are replaced due to disappearance or during sample rotations. This introduces a systematic bias in the measurement of inflation. For our data we find that the life cycle bias leads to the underestimation of inflation by around 0.30 percentage points each year for the products examined.     

Global instability in experimental general equilibrium: the Scarf example

Scarf (Int. Econ. Rev. 1 (1960) 157) proposed a model of dynamic adjustment in which the standard tatonnement price adjustment process orbits around, rather than converges to, the competitive equilibrium. Hirota (Int. Econ. Rev. 22 (1981) 461) characterized the price paths. We explore the predictions of Scarf's model in a non-tatonnement experimental double auction. The average transaction prices in each period do follow the path predicted by the Scarf and Hirota models. When the model predicts convergence the data converge; when the model predicts orbits, the data orbit in the direction predicted by the model. Moreover, we observe a weak tendency for prices within a period to follow the path predicted by the model.     

THE DECLINE OF JAPAN'S SAVING RATE AND DEMOGRAPHIC EFFECTS*

This paper investigates the phenomenon in which Japan's household saving rate showed a sharp decline even during the long stagnation period called “the lost decade.” Our empirical results show that the sharp decline in the saving rate in the 1990s can be explained by the significant impact of demographic factors. Furthermore, the estimated life cycle curve is hump shaped, meaning that the prediction of the life cycle model is confirmed with time series data on the Japanese saving rate.     

REGIME DEPENDENT EFFECT OF OUTPUT GROWTH ON OUTPUT GROWTH UNCERTAINTY: EVIDENCE FROM OECD COUNTRIES

This paper studies the impact of output growth on output growth uncertainty by considering two important issues hitherto not properly and adequately addressed to in the existing empirical studies specifying this relationship. These are: (i) the possible existence of a threshold level of output growth, and the consequent identification of two regimes characterized by high and low output growth, and (ii) whether or not the coefficient capturing the causal link is different in these two output growth states. This paper proposes a regime switching model to study this asymmetric effect for 16 OECD countries. Based on monthly time‐series observations, our results strongly support that the impact varies significantly between the two output growth regimes with the coefficient in the high growth regime being negative for majority of the countries.     

Introduction to internally consistent modeling,aggregation, inference,and policy

This special issue of the Journal of Econometrics honors William A. Barnett’s exceptional contributions to unifying economic theory with rigorous statistical inference to interpret economic data and inform public policy. It is devoted to papers that advance microeconometrics, macroeconometrics, and financial econometrics to build models to interpret evidence.     

Sustainability, flexibility, and inflation targeting

This paper examines sustainability of an inflation-targeting policy regime in terms of sustainable equilibrium using a canonical model in the recent literature. Overly flexible inflation targeting is not sustainable. Strict inflation targeting is sustainable only when shock persistence is high enough.     

A New Measure of Disclosure Quality: The Level of Disaggregation of Accounting Data in Annual Reports

We construct a new, parsimonious, measure of disclosure quality—disaggregation quality (DQ)—and offer validation tests. DQ captures the level of disaggregation of accounting data through a count of nonmissing Compustat line items, and reflects the extent of details in firms’ annual reports. Conceptually, DQ differs from existing disclosure measures in that it captures the “fineness” of data and is based on a comprehensive set of accounting line items in annual reports. Unlike existing measures, which are usually applicable for a subset of firms or are based on a subset of information items, DQ can be generated for the universe of Compustat industrial firms. We conduct three sets of validation tests by examining DQ's association with variables predicted by prior literature to be associated with information quality. DQ is negatively (positively) associated with analyst forecast dispersion (accuracy) and negatively associated with bid‐ask spreads and cost of equity. These associations continue to hold after we control for firm fundamentals. Taken together, results from this battery of validation tests are consistent with our measure capturing disclosure quality.     

Monetary and Fiscal Policy Rules in the EMU

Abstract. This paper studies the design and effects of monetary and fiscal policy in the euro area. To do so, a stylized two‐region model of monetary and fiscal policy rules in the EMU is built. We analyse how monetary and fiscal rules affect the adjustment dynamics in the model. Both the effects on the individual countries and on the EMU aggregate economy are studied. Three aspects play an important role in the analysis: (i) the consequences of alternative monetary and fiscal policy rules, (ii) the consequences of asymmetries between EMU countries (asymmetries in macroeconomic shocks and macroeconomic structures), and (iii) the role of alternative degrees of backward‐ and forward‐looking behaviour in consumer decisions and inflation expectations.
