We develop a tractable rational bubbles model with financial frictions, downward nominal wage rigidity, and the zero lower bound. The interaction of financial frictions and nominal rigidities leads to a "bubbly pecuniary externality," where competitive speculation in risky bubbly assets can...

Since decades, only one fourth of German households invest in shares. One exception was during the three IPOs from 1996 to 2000 of the Deutsche Telekom, which gave Germans a taste to enter the stock market. However, the fall in the share price shortly after the second IPO, followed by corruption...

Why are asset prices so much more volatile and so often detached from their fundamental values? Why does the bursting of financial bubbles depress the real economy? This paper addresses these questions by constructing an infinite-horizon heterogeneous agent general equilibrium model with...

The study quantifies stock market and housing market wealth effects on households' non-durable consumption using Italian household panel data (SHIW) of 1989-2002. We found all households react similarly to aggregate housing and stock market gains. We also found statistically and economically...

This paper estimates the wealth effects on consumption in the euro area as a whole. I show that: (i) financial wealth effects are relatively large and statistically significant; (ii) housing wealth effects are virtually nil and not significant; (iii) consumption growth exhibits strong...

This paper adds to the literature on wealth effects on consumption by disentangling financial wealth effects from housing wealth effects for the euro area. We use two macro-datasets for our estimations, one on the aggregate euro area for the period 1980-2006, and one on the individual euro area...

This paper documents the asset pricing implications of the data release process of National Income and Product Accounts (NIPA) consumption expenditure. We show that initial consumption data releases are more suitable for asset pricing than final revised releases. This is because most revisions...

We provide evidence of the stock market wealth effect on consumption by using a local labor market analysis and regional heterogeneity in stock market wealth. An increase in local stock wealth driven by aggregate stock prices increases local employment and payroll in nontradable industries and...

We show how product variety affects asset prices in a general-equilibrium model. We analytically characterize the unique equilibrium and estimate the model to match asset pricing and product market moments. The equity premium and risk-free rate can be reconciled for risk aversion levels around 4...
