We provide a model of hedge fund securing financing from a prime broker where deterioration in collateral value exacerbates counterparty risk and liquidity risk for the prime broker due to strategic actions of hedge funds. Costs of liquidity insurance and enforcing contracts determine hedge fund leverage. The model provides several new insights. First, it uncovers a new channel for funding liquidity that can explain why illiquid funds fare worse in times of stress and why better governed funds fared better during the financial crisis. Second, the model provides a new testable hypothesis that systematic or idiosyncratic shocks to fundamentals of bank holding companies may spillover to connected hedge funds through internal capital markets. It also offers an identification strategy to distinguish between possible competing hypotheses. Third, strong governance at hedge funds may reduce incentives to invest in profitable opportunities. Fourth, banking reforms such as Supplementary Leverage Ratio, Liquidity Coverage Ratio and Standing Repo Facility intended to improve resilience of banks may also make hedge funds less vulnerable to shocks in the banking sector. Fifth, the model offers a possible reconciliation for the mixed evidence on the impact of leverage on hedge fund survival documented in the literature.

鉴于金融收益率数据存在的分布有偏、高峰厚尾以及不对称等特点导致传统分布难以对其进行描述。本文基于广义自回归得分（ GAS ）理论改进了非对称拉普拉斯分布 (ALD) ，提出了GAS-ALD 模型，该模型具有时变参数，可以描述具有高峰厚尾、有偏以及分布不对称性等特点的数据。并使用该模型对上证指数、深圳指数与中小板指数进行了实证研究。研究发现： 三个指数的分布参数与各阶矩均有明显的时变特征与聚集特征；对比了常用的用于计算 VaR与 ES 的模型， GAS-ALD 模型对于 VaR 与 ES 具有较高的预测效力。

This paper investigates the consequences of liquidation and reorganization on the allocation and subsequent utilization of assets in bankruptcy. Using the random assignment of judges to bankruptcy cases as a natural experiment that forces some firms into liquidation, we find that the long-run utilization of assets of liquidated firms is lower relative to assets of reorganized firms. These effects are concentrated in thin markets with few potential users, and in areas with low access to finance. The results highlight the importance of local search frictions and financial frictions in affecting the allocation of assets in bankruptcy.

China's stock market (the "A share market'') has a lower correlation with the global market and is less affected by international financial contagions than any other major economy. The inclusion of mainland China stocks into an international portfolio increases its Sharpe ratio. However, we find that Chinese stocks providing the most diversification benefits also carry the most policy risk for international investors. Holding Chinese stocks listed in Hong Kong does not reap the same diversification benefits. While global market integration and the increase in foreign ownership can diminish diversification benefits, mainland China stocks still provide valuable diversification opportunities for international investors up till the most recent time in late 2010s.

We provide direct evidence of leverage-induced fire sales contributing to a market crash using account-level trading data for brokerage- and shadow-financed margin accounts during the Chinese stock market crash of 2015. Margin investors heavily sell their holdings when their account-level leverage edges toward their maximum leverage limits, controlling for stock-date and account fixed effects. Stocks that are disproportionately held by accounts close to leverage limits experience high selling pressure and abnormal price declines which subsequently reverse. Unregulated shadow-financed margin accounts, facilitated by FinTech lending platforms, contributed more to the crash despite their smaller asset holdings relative to regulated brokerage accounts.

We analyze the effects on Chinese firms of the "China Connect" equity market liberalization. Because China is a capital abundant country, unlike typical emerging markets in the literature, the benefits and costs of liberalization are logically different. Nonetheless, the liberalization brought benefits: lower funding costs, higher stock prices, and more investment for connected firms compared to unconnected firms, despite a common negative effect on all firms from capital outflows. These benefits come from a new channel: reducing domestic credit misallocation between private- and state-owned enterprises. We also document costs: connected firms became more sensitive to external shocks than unconnected firms.

Fluctuations in investor demand dramatically affect firms' valuation and access to capital. To quantify its real impact, we develop a dynamic investment model that endogenizes both the demand- and supply-side of capital. Strong investor demand elevates equity prices and dampens price impacts of issuance, facilitating investment and financing, while weak investor demand instead incentivizes firms to optimally repurchase shares at favorable prices, which can crowd out investment, especially among firms with liquidity constraints. We estimate the model using indirect inference by matching the endogenous relationship between investors' portfolio holdings and firm characteristics. Our estimation suggests that investor demand substantially distorts firms' real investment decisions and impedes the efficient capital allocation across firms. Eliminating excess demand reduces dispersion in the marginal product of capital by 10.74% and TFP losses by 16.20%. Investor demand also influence firm size distributions and generates a heavy right tail---large excess demand provides firms with market power and opportunities to profit from their financial market activities, contributing to the emergence of superstar firms.

Using a difference-in-differences approach, we examine the effect of industry-specific knowledge transfer on audit performance after a merger of two Chinese audit firms with different levels of expertise in an industry. For clients in an industry audited by both merging audit firms, those audited by the audit firm less specialized in that industry belong to the treatment group, while all other clients belong to the control group. We find an economically-significant improvement in audit quality (as reflected in a reduction in financial misstatements) for the treatment group relative to the control group in the same merged audit firm. We show that the treatment effect is not driven by changes in auditor incentives or personnel movement and is more pronounced when we expect stronger communication between the less and more specialized auditors after the merger. We caution that our findings are specific to China and may not generalize to other countries.

Over the past twenty years, especially the past decade, China has taken enormous strides to develop its bond market as an integral step of financial reform. This paper aims to provide the most up-to-date overview of Chinese bond markets, by highlighting two distinct and largely segmented markets: Over-the-Counter based interbank market, and centralized exchange market. We explain various bond instruments traded in these two markets, highlighting their inherent connection with the banking system, and many multi-layer regulatory bodies who are interacting with each other in an intricate way. We also covers the credit ratings and rating agencies in Chinese market, and offer an account of ever-rising default incidents in China starting 2014. Finally, we discuss the recent regulatory tightening of shadow banking since late 2017 and its impact on bond investors, and the forces behind the internalization of Chinese bond markets in the near future.

Using data from 56 nations over 45 years, we find that nations that are more likely to elect left wing governments face higher (and more volatile) sovereign spreads. To explain these facts, we build a sovereign default model in which two policymakers (left and right) alternate in power. The probability of an incumbent staying in power is increasing in the share of government spending. We parametrize the left policymaker as having a higher marginal political gain from increasing government spending than the right does, a feature found in our data. Model economies in which the left is more frequently in power face worse borrowing terms due to higher default risk, a greater reluctance for fiscal austerity in bad times, and a higher share of government spending on average. These features imply large welfare losses for households.
