We study how firms decide whether to continue an existing relationship or switch the vendor of outsourced services. Because of incomplete contracts and relationship-specific investments, client organizations may face switching costs, which in some cases may be large enough to render vendor...

The presence of sticky, often labelled ‘unengaged', consumers is arguably one of the most intractable issues faced by competition regulators, in that it entrenches incumbency advantage. We develop a spatial linear model of heterogeneous switching costs that allows for asymmetric distributions...

We study asset pricing with consumption frictions. Frictions in consumption include adjustment costs which prevent a consumer from adjusting consumption freely, due to transaction costs, commitments, search and learning costs, and psychological costs. The stochastic discount factor is determined...

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

In this paper we introduce price search decision to a life cycle model, and differentiate consumption from expenditure. The consumers with low wealth and bad income shocks search more and pay less which makes their consumption higher than a model without search option. A plausibly calibrated...
