This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to 'unretire', i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

We present a model in which two of the most important features of the long-run growth process are reconciled: the massive changes in the structure of production and employment; and the Kaldor facts of economic growth. We assume that households expand their consumption along a hierarchy of needs...

The relationship between our general equilibrium model with multimember households and club models with multiple private goods is investigated. The main distinction in the definitions consists of the equilibrium concepts. As a rule, competitive equilibria among households where no group of...

This paper studies advertising in vertically differentiated product markets with positive consumption externalities. In markets with consumption externalities, the value of the product to the consumer depends on the purchasing decisions of other consumers. In such markets, we show that firms...

The aim of this Paper is to demonstrate that advertising can have an important function in markets with consumption externalities, apart from its persuasive and informative roles. We show that advertising may function as a device to coordinate consumer expectations of the purchasing decisions of...

This paper proposes a dynamic risk-based model that captures the high expected returns on value stocks relative to growth stocks, and the failure of the capital asset pricing model to explain these expected returns. To model the difference between value and growth stocks, we introduce a...

Models of shrouding predict that firms lack incentives to compete on add-on prices. Working with a large Turkish bank to test SMS direct marketing promotions to 108,000 existing checking account holders, we find that messages promoting a large discount on the overdraft interest rate reduce...

Motivated by the success of internal habit formation preferences in explaining asset-pricing puzzles, we introduce these preferences in a life-cycle model of consumption and portfolio choice with liquidity constraints, undiversifiable labour income risk and stock-market participation costs. In...

We investigate the implications of changes in the structure of the US economy for monetary policy effectiveness. Estimating a VAR over the pre- and post-1980 periods, we provide evidence of a reduced effect of monetary policy shocks in the latter period. We estimate a structural model that...

This Paper generalizes the standard habit formation model to an environment in which agents form habits over individual varieties of goods as opposed to over a composite consumption good. We refer to this preference specification as ‘deep habit formation’. Under deep habits, the demand...
