We analyze the incidence of ad valorem and unit excise taxes in an oligopolistic industry with differentiated products and price-setting (Bertrand) firms. Both taxes may be passed on to consumers by more than 100 percent, and an increase in the tax rate can increase short run firm profits (and...

This paper analyzes the incidence of ad valorem and unit excise taxes under imperfect competition with differentiated products and price-setting (Bertrand) firms. Both taxes may be overshifted onto consumers, and a higher tax rate can increase short run firm profits (and hence the long run...

This paper presents a spatial model to study imperfect competition with congestion. The model is used to examine the price and wage setting of subcenters of a city. Residents live in a city while they shop and work in subcentres. Each subcenter offers one differentiated product and one...

Full paper available at "https://ssrn.com/abstract=3141041" https://ssrn.com/abstract=3141041We first present simulations investigating some properties of the Inverse Product Differentiation Logit (IPDL) model. Next, we provide a range of general methods for building Generalized Logit (GL)...

We propose the Inverse Product Differentiation Logit (IPDL) model, a structural (inverse) demand model for differentiated products that captures market segmentation along several possibly overlapping dimensions. It generalizes the nested logit model to allow richer substitution patterns,...

In a vertically differentiated durable goods duopoly, prices tend to decline over time because the high-quality manufacturer's future product may compete more directly with the other firm's present product than with its own. This removes the standard reason not to cut prices (Stokey, 1979)....

Equilibrium prices behave quite differently if consumers single-purchase (buy either Time Magazine or Newsweek) or if some consumers multi-purchase (buy both). Prices are strategic complements under single-purchase, and increase with magazine quality. In a multi-purchase regime prices are...
