A model is presented to characterise the (optimal) demand for cash balances in deregulated markets. After the model of James Tobin, 1958, net balances are determined in order to maximise the expected return of a certain portfolio combining risk and capital. Unlike the model of Tobin, the prices...

An alternative theoretical setting is presented to characterise the money demand and the monetary equilibrium. Two main hypotheses are stated that contradict the assumptions normally sustained by scholars and policy-makers: National output is assumed to be a random variable, and people are...

This paper incorporates two features of housing in a life-cycle analysis of social security: housing as a durable good and housing market frictions. We find that with housing as a durable good unfunded social security substantially crowds out housing consumption throughout the life cycle. By...

Homotheticity induces a dramatic statistical bias in the estimates of the intratemporal and intertemporal substitutions. I find potent support in favor of nonhomotheticity in aggregate consumption data, with nondurable goods being necessities and durable goods luxuries. I obtain the...

An evolutionary model of the product life cycle is applied to derive the experience curve and the market size of (expensive) durable goods. The experience (learning) curve suggests that the real costs per unit decrease with an increasing cumulative output (Henderson's law). Based on the idea...

According to the hypothesis of planned obsolescence, a durable goods monopolist without commitment power has an excessive incentive to introduce new products that make old units obsolete, and this reduces its overall profitability. In this paper, I reconsider the above hypothesis by examining...

It was demonstrated that the difference between the PPI of durable and nondurable goods can be predicted at a several year horizon. The prediction consists of three steps. First, we show that the difference between producer price index for durable and nondurable goods is characterized by the...

I present a consumption-based asset pricing model that is capable of matching the empirically observed Sharpe ratios of the aggregate market portfolio as well as the Fama-French value-minus-growth portfolio. The model also matches the level of the risk-free rate and the equity premium with a...

We quantitatively investigate the allocative and welfare effects of secondary markets for cars. An important source of gains from trade in these markets is the heterogeneity in the willingness to pay for higher-quality (newer) goods, but transaction costs are an impediment to instantaneous...

Homotheticity induces a dramatic statistical bias in the estimates of the intratemporal and intertemporal substitutions. I find potent support in favor of nonhomotheticity in aggregate consumption data, with nondurable goods being necessities and durable goods luxuries. I obtain the...
