The impact of transaction costs on asset pricing in equilibrium is rarely studied. We study an equilibrium model with proportional transaction costs where two investors trade in a derivative to hedge non-traded endowments. For any positive transaction cost there always exist no trade equilibria....

We develop a general equilibrium model of cryptocurrency to study a double spending prevention mechanism without payment confirmations. Agents trade the cryptocurrency using a digital wallet, and the cryptocurrency system provides a way to verify a wallet's double spending history. Double...

Volatility trading is in vogue. Launched in January 2009, exchange-traded products (ETPs) linked to the CBOE Market Volatility Index (VIX) have enamored no small number of traders judging by the billions of dollars invested in these new products. Why exactly is unclear. The most popular VIX ETPs...

We present a dynamic microstructure model where a dealer market (DM) and a crossing network (CN) interact. Sequentially arriving traders with different valuations for an asset maximise their profits either by trading on a DM or by submitting an order for (possibly) uncertain execution via a CN....

Transaction costs play a significant role in financial markets, and many studies have been conducted on this topic to date. Research on this topic may be divided into two categories. The first category of studies examines the optimal trading strategy of the investor who has to pay transaction...

We derive allocation rules under isoelastic utility for a mixed jump-diffusion process in a two-asset portfolio selection problem with finite horizon in the presence of proportional transaction costs; we allow cash dividends on the risky asset. The allocation shifts toward the riskless asset...

We derive allocation rules under isoelastic utility for a mixed jump-diffusion process in a two-asset portfolio selection problem with finite horizon in the presence of proportional transaction costs. We adopt a discrete time formulation, let the number of periods go to infinity, and show that...

We investigate the role that transaction fees play in the Bitcoin blockchain's evolution from a mining-based structure to a market-based ecology. We develop a game-theoretic model to explain the factors leading to the emergence of transactions fees, as well as to explain the strategic behavior...
