Does Central Bank Financial Strength Really Matter for Inflation? The Key Role of the Fiscal Support

This paper examines whether weak central bank finances affect inflation by scrutinizing the key rationale for such a relationship: that the absence of Treasury support makes central bank finances relevant for price stability. Specifically, I ask whether central banks which are not likely to enjoy fiscal support when needed experience higher inflation as their financial situation deteriorates. I find this to be true among a large sample of 82 countries between 1998 and 2008. De facto potential fiscal support appears relevant, while de jure fiscal support, which I survey analyzing 82 central bank laws, does not appear to matter. The results also bring forward an explanation for the conflicting results of the previous empirical studies, which neglected this key component.     

Assessing Productivity Gains from International Trade in a Small Open Economy

Empirical evidence suggests that exporter firms tend to charge higher markups than non-exporters due to trade barriers. The exporters’ markup premium, however, may disappear in a special case, namely when the home country is small relative to its trade partners and trade barriers are low. This can be because competition is more intense in the large export destination than in the small home country, so that firms are able to set higher markups for locally sold products but not for exports. This paper provides empirical evidence on the validity of this special case by estimating markups for firms in Luxembourg who generally export to larger countries. The estimated negative markup premium for exporters has important implications for the productivity measurement. In a sufficiently small open economy, exporters’ productivity may be biased downward, when the firm-level markup variation is not controlled for in the productivity estimation. The bias in the productivity estimates further leads to the inaccurate conclusion that openness to international trade lowers allocative efficiency.     

Corporate Governance and CEO Innovation

A fundamental concern emerging from the corporate literature is the agency problem of innovation. While innovation is considered as a major driver of corporate growth and profitability, the Chief Executive Officer (CEO) has an intrinsic reluctance to pursue innovation projects. The thrust of this paper is to identify the mechanisms of corporate governance which help attenuate this problem, thereby encouraging the CEO to have the propensity to innovate. The empirical results suggest that firms with a widespread dispersion of shares among shareholders are less likely to encourage the CEO to innovate. The likelihood of innovation appears to increase, however, in the presence of a large shareholder. Contrary to prevailing beliefs, there appears to be no association between innovation and board independence. The same result holds for board size. Also, a diverse board appears to negate CEO predisposition to innovate. On the other hand, innovation increases when the CEO is not the Board Chair but has equity ownership, although the incentive effect is economically small. The paper uses a sample of domestically-owned, publicly-listed Australian firms over the period 1994–2003.     

Estimating Key Economic Variables: The Policy Implications

The current monetary policy debate has focused on current estimates and the future path of the natural rate of unemployment and the equilibrium interest rate. Estimates of the natural rate of unemployment should vary over time with changes in demographics and improvements in human capital. However, these changes should be gradual. This paper shows that the estimates of the natural rate of unemployment by Federal Reserve officials and private-sector economists seem to move pro-cyclically, potentially showing too much weight given to short-term fluctuations in economic variables. As with the natural rate, there are good reasons to expect the equilibrium interest rate to change over time. In fact, the level may actually be more responsive to current economic data, reflecting changes in aggregate savings and investment. Yet, we see that equilibrium interest rate estimates by both Federal Reserve officials and private-sector economists have declined quite dramatically over the past five years. A potential concern raised in this paper is that estimates of these critical economic variables for policy determination appear to be overly sensitive to high frequency economic data.     

Investing in Health: A Macroeconomic Exploration of Short-Run and Long-Run Trade-Offs

This paper aims to unravel the competing effects of health investment. It explores, both analytically and numerically, the equilibrium shift and transitional dynamics after a one-time policy of health investment. We find that such a policy improves health status in the long run, but harms economic growth in both the short- and long-term. The relative sizes of these competing effects depend on the specific health parameters. Within the plausible range for the value of health relative to consumption, households gain welfare in the long run as long as the effectiveness of labor in health production is large. The expanded health sector policy makes households worse off only if labor is rather unproductive in producing health and if households value health relatively little. Nevertheless, the findings challenge the policy recommendations of the World Bank (1993) and World Health Organization (2001) in that good health does not necessarily increase the productivity of workers and the economic growth rate. We hope that the relative simplicity of our model, compared to the existing theoretical literature, can help close the gap between formal academic work on this topic and actual debates among policy makers in both developed and developing countries.     

Migration,FDI, and Welfare

We investigate migration and foreign direct investment (FDI) for a small trading economy. Historically, immigration in small countries has been accompanied by FDI inflows (complementary capital movements). Based on the skill composition of migrants, empirical evidence finds that skilled immigration is accompanied by FDI inflows but unskilled immigration is accompanied by FDI outflows (substitutable capital movements). We prove that the Heckscher-Ohlin model cannot reconcile these apparently contradictory observations. We introduce a theoretical model in which capital and unskilled labor are sector specific, and demonstrate that this model can reconcile the historical and empirical observations on migration and FDI.     

Why Are Input-Output Tables Important?

The new input-output tables published by Rosstat for 2011–2015 are indeed an achievement worth celebrating. These tables form a comprehensive picture of the economy that show how its many parts are connected. They serve as a basis for national accounts and for envisioning possible futures for the economy.     

International capital mobility: regional versus global perspective

This paper examines the role of regional versus global savings in financing domestic investment to shed light on the role of financial globalization and regionalism in capital markets. Regression results based on six regions with 141 countries reveal that although the role of foreign (global or regional) saving has increased over time, there are regional differences: domestic saving is the major source of investment financing in North America with an increasing role of regional and global savings over time, while regional saving is the main source in Europe. Global saving has been the main source of investment financing in other regions where domestic and regional financial markets are not well developed. However, the role of regional saving has significantly increased in recent years in the Asia-Pacific and in Latin America. Regionalism such as financial and monetary cooperation is likely to have increased the role of regional saving.
