This paper formalizes an empirically implementable framework for the definition of local antitrust markets in retail markets. This framework rests on a demand model that captures the trade-off between distance and pecuniary cost across alternative shopping destinations within local markets. The paper develops, and presents estimation results for, an empirical demand model at the store level for...

Abstract We investigate how capital requirements affect loan rates by studying the 50% increase in risk weight for high volatility commercial real estate (HVCRE) loans under Basel III. Exploiting variation terms and exposure to period after rule’s implementation, we find that a one-percentage-point raises 8.5 basis points. Using model of bank funding costs, demonstrate timing scope HVCRE rule i...

In this paper we argue that two important causes of welfare losses in oligopolistic markets have been neglected. We show that in models where location is endogenous, welfare losses arising from wrong locations or from lack of market coverage may be substantial despite firms competing in prices. In contrast, welfare losses arising from quality choice are modest but they might vary discontinuousl...

Competition authorities have a growing interest in assessing the effects of partial ownership arrangements. We show that the effects of such agreements on competition and welfare depend on the intensity of competition in the market and on the firms’ governance structure. When assessing the effects of partial ownership, competition policy has to consider both the financial interest and level of ...

We argue that there exists a problem of adverse selection in the provision of advertising which makes it impossible to establish direct markets for it. The media are regarded as intermediaries that can channel advertising and allocate it efficiently by screening consumers. This role of media may result in excessive quality and prices of media products. These distortions will be more severe if c...

We use microdata collected at the border and store to characterize price impact of recent US trade policy on importers, exporters, consumers. At border, import tariff pass-through is much higher than exchange rate pass-through. Chinese exporters did not lower their dollar prices by much, despite appreciation dollar. By contrast, significantly lowered affected foreign retaliatory tariffs. In sto...

Macro-prudential authorities need to assess medium-term downside risks the real economy, caused by severe financial shocks. Before activating policy measures, they also consider their short-term negative impact. This gives rise a risk management problem, an inter-temporal trade-off between expected growth and risk. Predictive distributions are estimated with structural quantile vector autoregre...

A central question in the analysis of fuel economy policy is whether consumers are myopic with regards to future costs. We provide first evidence on consumer valuation from a natural experiment that provides exogenous variation ratings. examine short-run equilibrium effects restatement ratings affected 1.6 million vehicles. Using implied changes willingness pay, we find act myopically: indiffer...
