Economists have long known that time scale matters in that the structure of decisions as to the relevant time horizon, degree of time aggregation,strength of relationship, and even the relevant variables differ by time scale. Unfortunately, until recently it was difficult to decompose economic...

In this note, we consider the contradiction between the fact that the best fit for the UK consumption data in Davidson et al. (1978) is obtained using an equation with an intercept but without an error correction term, whereas the equation with error correction and without the intercept has...

The study examines the behaviour of imports of goods in the Greek economy during the last five decades and their determinants, with an emphasis on consumer’s preferences for “variety and quality” of the imported goods as well as on the demand and supply conditions of these goods in the...

Investigating stockholder consumption growth is critical in asset pricing studies, as preference and risk averse of stockholders differ from that of average households. The disagreement among households about the macroeconomic uncertainty leads to their heterogeneous stock market participation...

This paper presents a simple new method for measuring 'wealth effects' on aggregate consumption. The method exploits the stickiness of consumption growth (sometimes interpreted as reflecting consumption 'habits') to distinguish between immediate and eventual wealth effects. In U.S. data, we...

This paper studies the importance of intertemporal substitution in consumption for the cyclical co-movement of consumption, net worth and income. We can largely explain the empirical hump-shaped consumption response to a transitory wealth increase by allowing for time-varying returns in an...

We examine the importance of intertemporal substitution in U.S. import consumption using a model of permanent income that allows for random preference shocks and additive separability. The latter feature allows us to take two estimation approaches. In the first approach, we show that there is a...

This paper investigates whether there are variants of the permanent income model that are consistent with seasonally unadjusted quarterly postwar Canadian data. The analysis is based on a misspecification-test equation which nests the standard permanent income model. The results obtaineda re...

In the wake of a slump in gross savings due to macroeconomic shocks, among them the COVID-19 pandemic costs, this study examines to what extent inflation explains the variation in the saving culture in developing countries. Most past empirical studies investigated the role of inflation on...
