This paper measures energy efficiency improvements of US single-family homes between 1997 and 2001 using a two-stage procedure. In the first stage, an indicator of energy efficiency is derived by means of Data Envelopment Analysis (DEA), and the analogy between the DEA estimator and traditional...

In this study we introduce a new monthly indicator for private consumption in Germany based on search query time series provided by Google Trends. The indicator is based on unobserved factors extracted from a set of consumption-related search categories of the Google Trends application Insights...

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...

Information about special events can improve economic forecasts substantially. However, due to the lack of timely quantitative data about these events, it has been difficult for professional forecasters to utilise such information in their forecasts. This paper investigates whether Internet...

While recently more and more research has focused on the aggregate response of consumption to income shocks, little is known about how this response differs for households at different ends of the income distribution. This paper investigates how consumption reacts to transitory and permanent...

The purpose of this contribution is to illustrate the mechanism by which higher oil prices might lead to lower interest rates in the context of a simple model that takes into account the global external savings equilibrium. The simple model has interesting implications for how one views the huge...

Contrary to the implications of economic theory, consumption inequality in the US did not react to the increases in income inequality during the last three decades. This paper investigates if a change in the type of income inequality - from permanent to transitory - or a change in the ability to...

In this study, the relation between consumer credit and real economic activity during the Great Moderation is studied in a dynamic stochastic general equilibrium model. Our model economy is populated by two different household types. Investors, who hold the economy's capital stock, own the firms...

The development of expenditure for care services is one of the most intensively debated topics in public. However, studies calculating financial provision gaps only focus on the macro-level implications for the compulsory care insurance. In contrast, this paper examines the individuals'...
