Dybvig [1995] finds optimal spending and investment strategies for a perpetual endowment that has no tolerance for spending declines. His spending rule is a ratchet --- spending never decreases, but has a substantial chance of increasing. We find the ratchet consumption rule for an investor with...

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 investigates empirically the consumer demand of environmentally relevant goods for Germany, as well as their relationship to the demand for leisure. Higher prices for energy goods like gas, electricity or fuel oil due to higher indirect taxation amongst others may have serious welfare...

Excise duties are an important source of government revenue and their rates change relatively often in the Czech Republic. Reforms of excise duties change the prices of goods, a change to which households respond by adjusting their expenditures. I use detailed Czech Statistical Office data and...

A model of rational addiction (RA) with optimal inventories is developed and empirically tested using data on purchases in Japan. If a consumer has information regarding a future price increase, then she may hoard addictive goods; in this case, the optimal inventory period increases with the...

The rates of value added tax (VAT) have recently changed in the Czech Republic, and I simulate the impact of these reforms. They are an example of changes in indirect taxes that change the prices of goods and services, to which households can respond by adjusting their expenditures. I first...
