        SELECTED RECENT WORKING PAPERS:
          • A first analysis of asset pricing effects of the unique agency MBS market structure with parallel trading in TBA and SP markets: MBS heterogeneity positively affects expected returns and ratio of SP to TBA trading activities
          • Asset heterogeneity leads to market fragmentation and exacerbates search friction; a quasi-consolidated trading design, in which a cohort of heterogeneous assets are sold at the same price, promotes market liquidity by pooling multiple sellers and buyers together. 
          • The formation of (customer-dealer) OTC market structure with dealers' endogenous expertise acquisition  
        • Dealers as Information Intermediaries in Over-the-Counter Markets, with Wei Li    October 2019     
          • A simple theoretical framework to analyze the trading and information intermediation by dealers in their relationship network with customers in OTC markets
        • Agency MBS as Safe Assets, with Zhiguo He, September 2020, Revised    
          • A set of systematic evidence on the economic role of agency MBS as a major class of long-term safe assets, whose average convenience premium is about half of that for Treasury bonds.  
            • Two intermediary-based factors - an intermediary financial distress measure and a dealer corporate bond inventory measure - explain about 50% of the puzzling common variations of credit spread changes beyond canonical structural factors, consist with a stylized model of liquidity-providing dealers with margin/capital constrains of both the whole intermediary organization and the specific asset desks.   
            • Theoretical framework and empirical evidence on the effect of dealers' balance sheet constraints and costs on the Treasury-OIS spread and repo spread during the COVID-19 crisis, as well as the 2007-2009 financial crisis.
            • The US Treasuries' safe asset status is limited by dealers' balance sheet capacity in the current institutional design of Treasury market and post-crisis regulatory framework.
            • A combination of the "scramble-for-cash" liquidity shocks of investors and the balance sheet costs of dealers led to severe price dislocations --- widening basis of cash-forward arbitrage --- in the agency MBS market, while the Fed, in its role as the “dealer of last resort”, absorbed the liquidity demand that dealers lacked the capacity to meet.
            • Primary dealers accumulate MBS inventory from two months before the Fed's disclosed purchase date and a few large dealers acquire the bulk of inventory. In consequence, they charge large uncompetitive pricing: large dealers sell more MBSs and at higher prices to the Fed, and dealers charge discriminatory prices against the Fed relative to non-Fed customers. 
            • Theoretical and empirical analyses of issuers' strategies of packaging loans into mortgage-backed securities in response to the existence of the cohort-based TBA trading mechanism; the economic benefit is about 40% (15%) of the average trading cost for large (small) issuers.
