Firms can accumulate capital through either purchase of the existing capital or producing new capital by themselves. Firms need to borrow from financial intermediaries to finance their purchases of capital. With the presence of financial market frictions, firms have to pay an exter...

Abstract This paper studies arbitrage-free financial markets with bid-ask spreads whose super-hedging prices are submodular. The submodular assumption on the price, or supermodularity usually assumed utility functions, is formal expression of perfect complementarity, which dates back to Fisher, Pareto, and Edgeworth, according Samuelson (J Econ Lit 12:1255–1289, 1974). Our main contribution pro...

Optimal Price Indices for Targeting Inflation under Incomplete Markets 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 twosector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with financial frictions. Financial frict...

As a result, trading frictions induce firms to borrow and invest at shorter horizons than in a fr...
