The 'saving for a rainy day' hypothesis implies that households' saving decisions reflect that they can (rationally) predict future income declines. The empirical relevance of this hypothesis plays a key role in discussions of fiscal policy multipliers and it holds under the null that the...

This study examines the persistence of currency substitution in Nigeria by applying the Bounds testing approach to cointegration and including a ratchet variable in the estimated Autoregressive Distributed Lag (ARDL) model. Empirical results show that factors such as exchange rate risks,...

Real life applications of yardstick regulation frequently refer to historical cost data. While yardstick regulation cuts the link between firms own costs and prices firms may charge in a static setting, it does not do so in a dynamic setting where historical cost data is used. A firm can...

The `saving for a rainy day' hypothesis implies that households' saving decisions reflect that they can (rationally) predict future income declines. The empirical relevance of this hypothesis plays a key role in discussions of fiscal policy multipliers and it holds under the null that the...

A new theory of interest rates, the Neo-Fisherian theory, predicts a low inflation rate due to a central bank's low interest rate. After several years of near-zero interest rate policies and low and even negative infl ation rates in the eurozone and in the US, this theory gained momentum in...

This dissertation contains economic microanalyses of voting, regulation and higher education. It is about individual decisions, institutions, and the incentives the latter create. Three chapters of this dissertation are based on empirical results, whereas one chapter is a purely theoretical...

We demonstrate that upward-looking comparisons induce "keeping up with the richer Joneses"-behavior. Using data from the German Socio-Economic Panel, we estimate the effect of reference consumption, defined as the consumption level of all households who are perceived to be richer, on household...

We demonstrate that interpersonal comparisons lead to "keeping up with the Joneses"-behavior. Using annual household data from the German Socio-Economic Panel, we estimate the causal effect of changes in reference consumption, defined as the consumption level of all households who are perceived...

Real life applications of Yardstick Regulation frequently refer to historical cost data. While Yardstick Regulation cuts the link between firms own costs and prices firms may charge in a static setting, it does not in a dynamic setting where historical cost data is used. A firm can influence the...

This paper investigates the relationship between wealth, ageing and saving behaviour of private households by using pooled cross sections of German consumption survey data. Different components of wealth are distinguished, as their impact on the savings rate is not homogeneous. On average, the...

This paper studies the optimal public investment decisions in countries experiencing a resource windfall. To do so, we use an augmented version of the Permanent Income framework with public investment faced with adjustment costs capturing the associated administrative capacity as well as...

Over the last three decades, average income for the bottom half of the US distribution increased by 8% while their average saving rate decreased by eight percentage points. Over the same period the US experienced a substantial increase in inequality and a continuous decrease in the aggregate...

The life-cycle hypothesis implies that consumption would not decline at retirement. However, several studies found relevant declines in food consumption after retirement for the United States. Others concluded that this contradiction of the life-cycle hypothesis is solved by allowing for broader...

This paper empirically investigates the relevance of liquidity constraints and excess sensitivity in intertemporal household consumption. Using a pseudo panel that has been constructed on rich German consumption survey data, we estimate the consumption responses to permanent and transitory...

In his widely discussed book "Fault Lines" (2010), Raghuram Rajan argues that many U.S. consumers have reacted to the decline in their relative permanent incomes since the early 1980s by reducing saving and increasing debt. This has temporarily kept private consumption and thus aggregate demand...

According to the German SAVE survey, more than 40 percent of households regularly save fixed amounts rather than flexibly adjusting savings to income variations as assumed by the Permanent Income Hypothesis (PIH). Fixed amount saving behaviour could thus imply a challenge to PIH-based standard...

Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience...

This paper is an attempt to test the Permanent Income Hypothesis (PIH), Myopia and Liquidity Constraints as a case study for Pakistan. The paper also attempts to find out valid reasoning incase the PIH is rejected. Hall.s random walk model (1978) and Campbell and Mankiw model (1990) are used to...

We use individual and multi-level data from Zambia on child nutritional health to test the absolute income hypothesis (AIH), the relative income hypothesis (RIH) and the income inequality hypothesis (IIH). The results confirm a non-linear positive relation between economic resources and health,...
