The traditional normative analysis of government policy towards addictive bads is carried out in the context of a 'rational addiction' model, whereby the only role for government is in correcting the external costs of consumption of such goods. But available evidence is at least as consistent,...

The effects of income and consumption taxation are examined in the context of models in which the growth process is driven by the accumulation of human and physical capital. The different channels through which these taxes affect economic growth are discussed, and it is shown that in general the...

The central result of this paper is that when moral hazard ispresent,competitive equilibrium is almost always (constrained) inefficient. Moral hazard causes shadow prices to deviate from market prices. To remedy this market failure, the government could introduce differential commodity taxation....

A central assumption in public finance is that individuals optimize fully with respect to the incentives created by tax policies. In this paper, we test this assumption using two empirical strategies. First, we conducted an experiment at a grocery store where we posted tax-inclusive prices for...

In data from an account aggregator, households increase consumption when they receive (expected) tax refunds, as if they are liquidity constrained. However, this behavior is not due to liquidity constraints or hand-to-mouth behavior. These same households smooth consumption when making payments...

We derive testable implications of model in which first best allocations are not achieved because of a moral hazard problem with hidden saving. We show that in this environment agents typically achieve more insurance than that obtained under autarchy via saving, and that consumption allocation...

Standard international economic models with life cycle/permanent income consumption behavior predict that international portfolio diversification leads to high bilateral consumption correlations. Thus international consumption correlations have been empirically estimated as a test of...

The objective of the work reported in this paper is to find if the consumption data from the six waves of the Retirement History Survey are consistent with the life cycle hypothesis of consumption and to test the importance of a bequest motive for saving. The 12 data items which are used cover...

The marginal propensity to consume out of wealth is important for evaluating the effects of taxation on consumption, assessing the possibility of multiple equilibria due to aggregate demand spillovers, and explaining observed variations in consumption. It is also a component of the interest...
