Financial crises and interacting heterogeneous agents

In this paper we examine various types of financial crises and conjecture their underlying mechanisms using a deterministic heterogeneous agent model (HAM). In a market-maker framework, forward-looking investors update their price expectations according to psychological trading windows and cluster themselves strategically to optimize their expected profits. The switches between trading strategies lead to price dynamics in market that subsequently move price up and down, and in the extreme case, cause financial crises. The model suggests that both fundamentalists and chartists could potentially contribute to the financial crises.

Capital Controls in Brazil – Stemming a Tide with a Signal

Controls on capital inflows have been experiencing a renaissance since 2008, with several prominent emerging markets implementing them in recent years. We focus on Brazil, which instituted five changes in its capital account regime in 2008–2011. Using the synthetic control method, we construct counterfactuals (i.e., Brazil with no policy change) for each of these changes. We find no evidence that any tightening of controls was effective in reducing the magnitudes of capital inflows, but we observe some modest and short-lived success in preventing further declines in inflows when the capital controls were relaxed. We hypothesize that price-based capital controls’ only perceptible effect is to be found in the content of the signal they broadcast regarding the government’s larger intentions and sensibilities. In the case of Brazil, its left-of-center government’s willingness to remove controls was perceived as a noteworthy indication that the government was not as hostile to the international financial markets as many expected it to be.

Financial panic and emerging market funds

This article studies equity investment of emerging-market funds based on the 2003–2009 weekly data and compares the dynamics of flow and return between tranquil period and financial panic based on the experience of the latest 2008–2009 global financial crisis. First, we find that the well-documented positive feedback trading is a tranquil-period phenomenon such that it is more difficult in general for emerging-market funds to attract new investment in financial panic. Second, the predictive power of flow on return is driven by a combination of price pressure and information effects in tranquil period, while the information effect dominates in financial panic. Third, the underlying co-movements or contagion of flow across the emerging-market funds influence the association between flow and return. Overall, the findings highlight the importance of accounting for state-dependent dynamics as well as cross-regional co-movements in the analysis of flow and return.

Regime Switching Models in the Foreign Exchange Market

This chapter compares three regime-switching models in estimating and forecasting behavioural heterogeneity in the AUD/USD foreign exchange market. The three heterogeneous agent models allow different elements to be regime-dependent following different mechanisms. The first model pioneered by Boswijk et al. (2007) models the fraction of each type of agents as a function of its relative past performance. The second model developed by Lof (2012) allows agents to switch their strategies based on macroeconomic fundamentals. The third model proposed by Chiarella et al. (2012) sets agents beliefs to be dependent on a Markov-switching process. Our empirical results show that (i) the model by Lof (2012) provides the best in-sample estimation efficiency and (ii) the model by Boswijk et al. (2007) significantly outperforms the model by Lof (2012) in terms of out-of-sample forecasting accuracy, but not that by Chiarella et al. (2012) in the medium to long run.

Chinese Outwards Mercantilism – the Art and Practice of Bundling

The Global Financial Crisis (GFC) brought to the fore the limits of the Chinese export led-growth strategy and the need for Chinese rebalancing of its international business approaches. Our paper takes stock of what may be the new chapter of Chinese outward-mercantilism, which aims at securing a higher rate of returns on its net foreign asset position, leveraging its success in manufacturing exports, natural resource imports and RMB internationalization. Using micro-level project data and macroeconomic covariates, we find positive association of Chinese trade and financial flows with China’s outward direct investment (ODI). The relationship is stronger for ODI originated from the Chinese state-owned enterprises, and strengthened by the provision of RMB swap-line agreements with China’s trading partners. The evidences support the conjecture that Chinese ODI is bundled to trade and financial linkages with its investment and trading partners.

Behavioral heterogeneity in the Australian housing market

ABSTRACT We propose a heterogeneous agent model (HAM) of four groups of investors with Markov chain regime-dependent beliefs for the housing market. Within the Markov switching framework, we take into account how heterogeneous investors shift their trading behaviour in response to changes in housing market conditions. The model is estimated and compared with the benchmark rational expectation models using the Australian housing market data from 1982Q1 to 2013Q2. We find evidence of within- and between-group heterogeneity in the Australian housing market. We show that HAM with Markov switching beliefs provides a better in-sample estimation efficiency and outperforms the conventional rational expectation models in terms of out-of-sample prediction.

Measuring Systemic Risk Contribution of International Mutual Funds

This study provides new evidence of systemic risk contribution in the international mutual fund sector from 2000–2011. The empirical analysis tracks the systemic risk of 10,570 mutual funds investing internationally. The main findings suggest that the systemic risk contributions of international mutual funds are more than proportional given the fund’s size. Policy implications are discussed in terms of practicality of regulation, macroprudential approach, and risk-taking behavior of fund managers.

What Lessons Can Asia Draw from Capital Controls in Brazil During 2008-2012?

Driven by waves of foreign capital inflows and outflows, Indonesia, the Republic of Korea, and Thailand—among several other emerging markets—have resorted to capital control policy since 2006. Are capital controls effective? Controls on capital inflows have been experiencing a renaissance since 2008, with several prominent Asian and Latin American countries implementing them. This paper focuses on Brazil, which instituted five changes in its capital account regime over 2008–2011. It concludes that the effectiveness of capital controls should be viewed on a case-by-case basis, together with the political economy considerations, and other policy tools, i.e., foreign exchange intervention.
