Beyond segmentation: The case of China’s repo markets

Journal of Banking & Finance 2007 31(3), 939-954
This paper explores the reasons behind the discrepancy between interest rates in China’s two repurchase agreement (repo) markets, the interbank repo market and the exchange-traded repo market. The repo rates in the exchange market are at times, significantly higher than those in the interbank market, especially in the first three years of the 2000–2005 sample period. While market segmentation clearly hinders arbitrage, the causes of the repo rate discrepancy are related to the alternative investment opportunities available to market participants and to the volatility differences in the repo rates.

Presidential Particularism (and the Trump Anomaly): Evidence from Federal Contract Awards and Capital Markets

The Review of Corporate Finance Studies 2025 14(4), 1024-1057
We document presidential particularism in the allocation of U.S. federal government contracts. Firms in “Swing” and “Core” states receive disproportionately higher federal contracts during election cycles. Contracts peak in reelection years for incumbent presidents suggesting electoral and partisan motives. Awards to “Core” states fall relative to “Hostile” states in election years of the presidents’ second terms. Government agencies engage more aggressively in particularism when aligned with the president’s party. Particularism disappeared during the Trump presidency, with Hostile-state firms awarded more contracts. Market participants, who are slow to recognize the relationship between particularism and corporate earning, underreact to this phenomenon.

The impact of cultural distance on fund transfers in the internal capital market

Journal of Banking & Finance 2024 165, 107224 open access
This paper examines how cultural distance affects fund transfers in the internal capital market of multinational firms. The results show that a larger cultural distance significantly reduces internal fund transfers to foreign subsidiaries. These results are robust to alternative measures of cultural distance and different econometric specifications. External shocks do not affect the results. Further analysis shows that the negative cultural impact is driven mainly by the dimensions of power distance, individualism, and uncertainty avoidance. Furthermore, the effect of cultural distance on internal fund transfers is independent of subsidiary productivity, and a larger cultural distance exacerbates the negative impact of corporate diversification on firm value. Overall, our findings highlight the important role that culture plays in multinationals’ global operations.

The Role of Firm Factors in Demand, Cost, and Export Market Selection for Chinese Footwear Producers

Review of Economic Studies 2018 85(4), 2429-2461 open access
In this article, we use micro data on both trade and production for a sample of large Chinese manufacturing firms in the footwear industry from 2002 to 2006 to estimate an empirical model of export demand, pricing, and market participation by destination market. We use the model to construct indexes of firm-level demand, marginal cost, and fixed cost. The empirical results indicate substantial firm heterogeneity in all three dimension with demand being the most dispersed. The firm-specific demand and marginal cost components account for over 30% of market share variation, 40% of sales variation, and over 50% of price variation among exporters. The fixed cost index is the primary factor explaining differences in the pattern of destination markets across firms. The estimates are used to analyse the supply reallocation following the removal of the quota on Chinese footwear exports to the EU. This led to a rapid restructuring of export supply sources on both the intensive and extensive margins in favour of firms with high demand and low fixed costs indexes, with marginal cost differences not being important.

A Method to Estimate Discrete Choice Models That Is Robust to Consumer Search

Journal of Political Economy 2026 134(7), 1967-2022 open access
We state a sufficient condition under which choice data alone suffices to identify consumer preferences when choices are not fully informed. Suppose that: (i) the data generating process is a search model in which the attribute hidden to consumers is observed by the econometrician; (ii) if a consumer searches good j, she also searches goods which are better than j in terms of the non-hidden component of utility; and (iii) consumers choose the good that maximizes overall utility among searched goods. Canonical models will be biased: the value of the hidden attribute will be understated because consumers will be unresponsive to variation in the attribute for goods that they do not search. Under the conditions above and additional mild restrictions, an alternative method of recovering preferences using cross derivatives of choice probabilities succeeds regardless of the search protocol and is thus robust to whether consumers are informed. The approach nests several standard models, including full information. Our methods suggest natural tests for full information and can be used to forecast how consumers will respond to additional information. We verify in a lab experiment that our approach succeeds in recovering preferences when consumers engage in costly search.

Information Dissemination and the Monetary Policy Uncertainty Premium: Evidence from China

Journal of Banking & Finance 2025 171, 107371
This paper proposes a novel monetary policy uncertainty (MPU) measure aggregating information from policy communication, policy operation and news coverage. We find that the aggregate MPU measure significantly commands a negative risk premium in the cross-section of the Chinese stock market. Stocks with higher (lower) MPU beta, favored (avoided) for hedging against MPU shocks, contribute to the premium through their under-performance (outperformance). Our results remain robust after controlling for economic uncertainty, economic policy uncertainty, and monetary policy surprises. We further show that the aggregate MPU measure outperforms its individual components in both portfolio- and stock-level asset pricing tests.

Investable commodity premia in China

Journal of Banking & Finance 2021 127, 106127 open access
We investigate the investability of commodity risk premia in China. Previously documented standard momentum, carry and basis-momentum factors are not investable due to the unique liquidity patterns along the futures curves in China. However, dynamic rolling and strategic portfolio weights significantly boost the investment capacity of such premia without compromising its statistical and economic significance. Meanwhile, style integration delivers enhanced performance and improved opportunity sets. Furthermore, the observed investable premia are robust to execution lags, stop-loss, illiquidity, sub-period specifications, seasonality and transaction costs. They also offer portfolio diversification for investors. Finally, investable commodity premia in China reveal strong predictive ability with global real economic growth.
