How does hyperinflation shock the economy?: Panel VAR Approach
Jun-Hyun Ko and Hiroshi Morita
Using 48 country data for the period 1800-2010, we empirically investigate the effect of hyperinflations on the public debt, the primary surplus, and the real economy. Estimating a panel vector-autoregressive (VAR) model, we find that (i) hyperinflations permanently reduce public debt-to-GDP ratios; (ii) the reduction is closely related to the increase in the primary balances in response to hyperinflations; (iii) however, hyperinflations accompany dampening effects on the real economy, reducing GDP.

Effects of the Great East Japan Earthquake on Subjective Well-Being
Takuya Ishino, Akiko Kamesaka, Toshiya Murai and Masao Ogaki
Using a large panel data set that samples over 4000 Japanese, we analyze changes in people’s subjective well-being (happiness) and altruistic worldview before and after the Great East Japan Earthquake. As a result we find that 1) more people replied that their happiness improved after the earthquake than said it worsened, and also that 2) many more Japanese people became more altruistic since the earthquake, even in the most affected areas. One possible interpretation of these results is that an increase in altruism due to the earthquake spurred people to give to charity, which in turn increased their happiness. Our regression analysis yields results that are consistent with this story.

Reputation and Liquidity Traps
Can the central bank credibly commit to keeping the nominal interest rate low for an extended period of time in the aftermath of a deep recession? By analyzing credible plans in a sticky-price economy with occasionally binding zero lower bound constraints, I find that the answer is yes if contractionary shocks hit the economy with sufficient frequency. In the best credible plan, if the central bank reneges on the promise of low policy rates, it will lose reputation and the private sector will not believe such promises in future recessions. When the shock hits the economy sufficiently frequently, the incentive to maintain reputation outweighs the short-run incentive to close consumption and inflation gaps, keeping the central bank on the originally announced path of low nominal interest rates.

Post-Crisis Slow Recovery and Monetary Policy
Daisuke Ikeda and Takushi Kurozumi
In the aftermath of the recent financial crisis and subsequent recession, slow recoveries have been observed and slowdowns in total factor productivity (TFP) growth have been measured in many economies. This paper develops a model that can describe a slow recovery resulting from an adverse financial shock in the presence of an endogenous mechanism of TFP growth, and examines how monetary policy should react to the financial shock in terms of social welfare. It is shown that in the face of the financial shocks, a welfare-maximizing monetary policy rule features a strong response to output, and the welfare gain from output stabilization is much more substantial than in the model where TFP growth is exogenously given. Moreover, compared with the welfare-maximizing rule, a strict inflation or price-level targeting rule induces a sizable welfare loss because it has no response to output, whereas a nominal GDP growth or level targeting rule performs well, although it causes high interest-rate volatility. In the presence of the endogenous TFP growth mechanism, it is crucial to take into account a welfare loss from a permanent decline in consumption caused by a slowdown in TFP growth.

TCER (Tokyo Center of Economic Research) and Institute of Developing Economies (IDE-JETOR) plan to have a conference on “The Effects of Unconventional Monetary Policy on Emerging Economies”. As the theme shows, our main interest is to see what impacts recent unconventional monetary expansion in developed countries had on various emerging economies. We accept any paper that analyzes the related topics. The conference will be held at the University of Tokyo in March 2015. If you are interested in contributing a paper for the conference, send your first draft to email@example.com by the end of November 2014.
A special issue of the Developing Economies (DE) on the conference theme will be published under the Guest Editorship. Authors whose papers are presented at the conference are supposed to submit their papers to the DE special issue. Papers submitted for this special issue will undergo the normal journal reviewing process.
DE is an academic journal published by WILEY-BLACKWELL and has ISI impact factor. Its details are available at
