International income risk-sharing and the global financial crisis of 2008–2009

We examine the impact of the global financial crisis on the degree of international income and consumption risk-sharing among industrial economies using returns on cross-border portfolio holdings (e.g., debt, equity, FDI). We split the returns from the net foreign holdings as receipts (inflows) and payments (outflows) to investigate which of the two sides exhibited the greater resilience for income risk-sharing during the recent crisis. First, we find that debt delivered better risk-sharing than equity, mainly reflecting the deficit deterioration in EMU countries during the post-crisis period. FDI, by contrast, did not correspond to noticeable risk diversification. Second, separating output shocks into positive and negative components reveals that debt holding receipts (equity liability payments) performed better under negative (positive) realizations of the shock variable. Third, the unwinding of capital flows resulted in a sharp fall in income dis-smoothing via the debt liability channel in the new EU countries.     

WOULD AUSTRALIA–NEW ZEALAND BE A VIABLE CURRENCY UNION? EVIDENCE FROM INTERSTATE RISK‐SHARING PERFORMANCES

In this article, we first measure the potential welfare gains from perfect risk sharing among Australian states and New Zealand regions under possible unification. We show that New Zealand regions reap moderate gains from perfect risk sharing when they form a union with Australia, whereas for Australian states, the gains are somewhat similar to what they have attained at the intranational level. Second, we measure the extent of interstate risk sharing and intertemporal smoothing between the two countries. We are able to observe a substantial degree of intertemporal smoothing among Australian states and New Zealand regions, either alone or jointly, thus confirming the permanent income hypothesis. Further, unique to the risk‐sharing literature, we decompose the aggregate (nondiversifiable) output shocks into positive and negative components, in order to assess the strength of risk‐sharing mechanisms across business cycles. The study finds a virtual absence of risk sharing when Australia and New Zealand face negative aggregate fluctuations, raising doubts about the feasibility of the union, particularly during economic downturns.

Testing the theory of PPP for emerging market economies that practice flexible exchange rate regimes

This study aims to test the long-run validity of purchasing power parity by using Fourier quantile unit root and Fourier cointegration analyses for 12 emerging market economies that practice a flexible exchange rate regime. With the Fourier approach, structural breaks are modelled as a gradual and smooth process. Fourier quantile unit root test results show that real exchange rate series are stationary for Colombia, India, Philippines, Poland, South Africa, and Turkey. On the other hand, Fourier cointegration test results reveal that purchasing power parity is valid for Brazil, Colombia, India, Mexico, South Africa, Thailand, and Turkey.     

Partisan politics and election failure with ignorant voters

We analyze candidate competition when some voters do not observe a candidate's policy choice. Voters have a personality preference when both candidates offer the same policy. In equilibrium, the candidate with a personality advantage may get elected with a partisan policy even though his opponent's policy is preferred by all voters. The departure from the Downsian prediction is most pronounced when candidates have a weak policy preference and care mostly about winning the election. In that case, uninformed voters choose the candidate with the preferred personality even if electing this candidate implies a lower payoff on average.     

Spillover effects on the sectoral returns for australian and New Zealand equity markets

In this paper, we examine the return and volatility spillovers, together with the trend spillovers on the sectoral equity returns for Australian and New Zealand markets. We find that the return spillovers of industrial, local and global shocks have a limited effect on Australian and New Zealand sector returns, whereas the volatility spillovers play a significant role on explaining the volatility of sector equity indices. Furthermore, we discover that the volatility spillover effects of the global and industrial shocks are greater in magnitude for explaining the volatility of the Australian sectors than those of New Zealand, particularly basic materials, oil and gas, technology and telecom sectors. By employing the trend spillover model, we find that the volatility spillover effects of global sector indices have been increasing over the volatility of the Australian sectoral returns until now. This finding proposes that Australian sector equity market is more integrated with the world than the New Zealand counterpart.
