Did Civilian Granaries Affect Social Stability? Empirical Evidence from the Qing Dynasty (1817–1856)

Based on historical panel data of social instability, civilian granary and climate shocks in the 17 Provinces of the Qing from 1817 to 1856, this paper examines the correlation between social instability and civilian granary holdings. It shows that the civilian granary system reduced social instability in the Qing Dynasty, while climate shocks raised social instability. Moreover, this paper shows that civilian granaries mitigated the effects of climate shocks on social instability.     

Endogenous business cycles and Harrodian instability in an agent-based model

The article presents an original stock-flow consistent macroeconomic agent-based model with the aim to reexamine Harrod’s instability principle as an explanatory element of macroeconomic dynamics. The main findings are that bottom-up economic models can be subject to Harrodian instability and can produce endogenous cycles without introducing innovation waves, monetary wage spirals, or financial instability. Upward instability is stopped by the ceiling of full employment, and downward instability can be tamed by introducing an autonomous expenditure that feeds aggregate demand.     

Thy Neighbor's Curse: Regional Instability and Economic Growth

We show that regional instability, defined as politicalinstability in neighboring countries, has a strong negative effecton a country's economic performance. The magnitude of this negativeexternality is similar in size to that of an equivalent increasein domestic political instability. We also identify two mainchannels through which regional instability lowers economic performance.First, regional instability disrupts trade flows. The sharesof merchandise and manufactured trade are lower in countrieswith high regional instability. Second, regional instabilityleads to increased military outlays. Defense expenditures arehigher in countries with high regional instability. In contrast,the share of government expenditures allocated to education islower in countries with politically unstable neighbors. Our resultssuggest the existence of negative spillovers among politicallyunstable neighboring countries. These adverse regional influencesshould be taken into account when projecting the future economicperformance of countries. The evidence presented also suggeststhat the gains from reducing regional instability extend farbeyond the welfare of the country experiencing political unrest.Policies directed at settling current territorial disputes ina peaceful and orderly manner can have large beneficial effectsfor parties not directly involved in the conflict.     

Individualism and political instability

This paper examines the relationship between the individualism-collectivism dimension of culture and political instability using a dataset covering around 100 countries. To shed light on the causal effect of culture on political instability, the identification strategy exploits the variation in historical pathogen prevalence and the information provided by the genetic distance between countries. The results reveal that individualism has a negative and statistically significant impact on the degree of political instability, which means that this cultural trait contributes to making the political environment more stable. This finding is robust to the inclusion in the analysis of a substantial number of controls that may be correlated with both individualism and political instability, including other cultural dimensions. In fact, the relationship between individualism and political instability does not depend either on the specific measures used to quantify the level of individualism and political instability within the various countries or the estimation strategy adopted. The estimates also show that part of the observed effect of individualism is due to the impact of institutional quality, which acts as a transmission channel linking this cultural trait and political instability.

Inflation Expectations and the Stability Properties of Nominal GDP Targeting

Ball (1999) uses a small closed economy model to show that nominal GDP targeting can lead to instability. This paper extends Ball's model to uncover the role inflation expectations play in generating this instability. Allowing inflation expectations to be formed by the more general mixed expectations process, which encompasses Ball's model, we show that nominal GDP targeting is unlikely to lead to instability. We further show that in Ball's model where exact targeting causes instability that moving to inexact targeting restores stability.     

Structural financial instability and cyclical fluctuations

This paper introduces and discusses an heuristic model meant to clarify why and how economic instability may play a crucial role in a modern sophisticated monetary economy. In this model economic instability is specified in terms of structural instability rather than in the usual terms of dynamic instability. This different view of instability implies a different approach to the analysis of the dynamic behaviour of the economic system and of its structural changes. In particular, the qualitative changes in the economic behaviour of the economic system are seen not as purely exogenous as in the received view but as essentially endogenous. This approach is applied to the analysis of financial crises and of their impact on the fluctuations of a sophisticated monetary economy. The crucial variable, the degree of financial fragility of the economic units, is specified in terms of structural instability, and this implies that, beyond certain thresholds of its value, the qualitative characteristics of their dynamic behaviour change radically in such a way to produce cyclical, though fairly irregular, fluctuations. The interplay between these microeconomic fluctuations is sufficient to produce cyclical macroeconomic fluctuations whose characteristics and implications for policy are briefly examined.     

Earnings Instability and Tenure

We study the effect of tenure on earnings instability in Italy using the reforms of temporary employment contracts, which affected the average tenure of workers differentially across cohorts. We develop a model of earnings dynamics, and we exploit the variation of tenure and instability over time and across birth cohorts to estimate policy‐relevant parameters. Our results indicate that each year of tenure on the job reduces earnings instability by 11 percent; the drop is faster in the first three years of the match. Workers on a temporary contract have an earnings instability up to 100 percent higher than workers on a permanent contract.     

CROSS‐SECTIONAL VARIATION IN INDIVIDUALS' EARNINGS INSTABILITY

There has been considerable recent interest in earnings instability—the variability of workers' earnings around their expected earnings paths. While previous work has measured trends in instability, often to illuminate trends in inequality, this paper investigates the variation across workers. Data from the Panel Study of Income Dynamics reveal considerable differences in earnings instability across demographic and occupational characteristics, generally in accordance with prior expectations. These results can also be used to develop a person‐specific measure of instability for use in behavioral studies, and it is shown that the resulting metric correlates strongly with several decisions that are plausibly influenced by earnings risk.     

Financial Instability and the Credit Crunch of 1966

In an article in this journal, Edwin Dickens criticizes the financial instability hypothesis of Hyman Minsky. He contends that ''financial instability theorists'' explain the financial crisis in the US in 1966 as due to the forced sale of securities by commercial banks, but that the 1966 crisis was not due to such sales. Therefore, he says that Minsky's financial instability hypothesis is contradicted. In contrast, this article argues that the 1966 crisis was initiated by the sale of securities by banks, but that such a development was not due to increased financial fragility, and thus was not a necessary aspect of the financial instability hypothesis. While the specifics of the 1966 crisis are somewhat of an exception, the general pattern of financial crisis in the postwar period in the US is powerfully explained by Minsky's financial instability hypothesis.     

Political instability: Effects on financial development, roots in the severity of economic inequality

We here bring forward strong evidence that political instability impedes financial development, with its variation a primary determinant of differences in financial development around the world. As such, it needs to be added to the short list of major determinants of financial development. First, structural conditions first postulated by Engerman and Sokoloff (2002) as generating long-term inequality are shown here to have strong empirical support as exogenous determinants of political instability. Second, that exogenously-determined political instability in turn holds back financial development, even when we control for factors prominent in the last decade’s cross-country studies of financial development. The findings indicate that inequality-perpetuating conditions that result in political instability and weak democracy are fundamental roadblocks for international organizations like the World Bank that seek to promote financial development. The evidence here includes country fixed effect regressions and an instrumental model inspired by Engerman and Sokoloff’s (2002) work, which to our knowledge has not yet been used in finance and which is consistent with current tests as valid instruments. Four conventional measures of national political instability – Alesina and Perotti’s (1996) well-known index of instability, a subsequent index derived from Banks’ (2005) work, and two indices of managerial perceptions of nation-by-nation political instability – persistently predict a wide range of national financial development outcomes. Political instability’s significance is time consistent in cross-sectional regressions back to the 1960s, the period when the key data becomes available, robust in both country fixed effects and instrumental variable regressions, and consistent across multiple measures of instability and of financial development. Overall, the results indicate the existence of an important channel running from structural inequality to political instability, principally in nondemocratic settings, and then to financial backwardness. The robust significance of that channel extends existing work demonstrating the importance of political economy explanations for financial development and financial backwardness. It should help to better understand which policies will work for financial development, because political instability has causes, cures, and effects quite distinct from those of many of the key institutions most studied in the past decade as explaining financial backwardness.     

Political Instability and Economic Growth: UK Time Series Evidence

This paper tests for the influence of political instability on UK economic growth between 1961 and 1997. We construct six variables that quantify political instability and examine the effect on growth. The results suggest that there is a strong link. GARCH‐M models reveal negative effects of instability on growth and positive effects on growth uncertainty. Uncertainty in itself does not affect growth.     

The effects of transition and political instability on foreign direct investment inflows

This paper examines the effects of transition and of political instability on foreign direct investment (FDI) flows to the transition economies of Central Europe, the Baltics and the Balkans. We find that FDI flows to transition economies unaffected by conflict and political instability exceed those that would be expected for comparable West European countries. Success with stabilization and reform increased the volume of FDI inflows. In the case of Balkan counties, conflict and instability reduced FDI inflows below what one would expect for comparable West European countries, and reform and stabilization failures further reduced FDI to the region. Thus, we find that the economic costs of instability in the Balkans in terms of foregone FDI have been quite high.     

INCOME INSTABILITY AND THE RESPONSE OF THE SAFETY NET

This paper examines the response of safety net transfer and tax programs to earnings and income shocks across recessions since the early 1980s. Safety net programs in the United States are designed to dampen economic instability and maintain basic needs for families. Such programs, including TANF, SNAP (food stamps), and the Earned Income Tax Credit (EITC), have been tested during and between recessions of the past 30 years, including the recent 2007–2009 Great Recession. I use matched data in the March Current Population Survey (CPS) from 1980 to 2012 to estimate pre‐ and post‐transfer income instability over the 1980s, 1990s, and 2000s, as well as across recessions. The results are disaggregated by family structure, race, income, and education. Transfer programs are associated with lowered instability levels and flatter trend growth from 1980 to 2012 among socioeconomically disadvantaged subgroups, while the tax system reduces income instability for families in the top 40th percentile of the income distribution. Although the largest instability reductions occur among the poor, since 1980 the safety net appears less responsive to instability for the bottom income quintile, female‐headed families, and black families.

Macroeconomic Volatility,Institutional Instability and the Incentive to Innovate

This study investigates the channels through which macroeconomic and institutional instability hinders innovative investment undertakings financed by the domestic private sector. The analysis is based on a sample of 44 countries and considers various instability dimensions. The results suggest a negative impact of real, monetary and political instability on the aggregate level of R&D financed by the business sector. Thus, highlighting the importance of stable macro‐institutional environments in preventing avoidance or abandonment of private innovation undertakings.

Export instability and concentration in the less developed countries: A cross-sectional analysis

A model to explain export instability in the less developed countries is formulated and tested on a sample of 48 less developed countries between 1957 and 1969. The explanatory variables suggested are commodity and geographic concentration and the importance of oil in the export sector. These variable are defined in a variety of ways to determine the sensitivity of the results to variable definitions. The results suggest that all three explanatory variables are significant in explaining export instability, although a considerable proportion of the variance in export instability remained unexplained.     

Portfolio and wealth effects of bond finance and the stability of the monetarist policy rule

It is shown that the potential instability of the monetarist policy rule does not disappear if government bonds are not net wealth; on the contrary, portfolio balance effects make instability very likely for this case.     

Central bank independence,inflation and political instability in developing countries

We test whether political instability affects central bank independence in developing countries. Both a legal measure and the turnover tate of central bank governors are used as proxies for central bank independence and the frequency of government transfers is used to proxy political instability. Only the number of coups affects the turnover rate of central bank governors. We also find that both the turnover rate of central bank governors and political instability affect the rate of inflation.     

Analysis of non-stationary dynamics in the financial system

Novel data-driven analyses, appropriate for detecting economic instability in non-stationary time series, are developed using functional principal component analysis (fPCA) and Synchrosqueezing. fPCA is applied in a new way, aggregating multiple financial time series to identify periods of macroeconomic instability. Synchrosqueezing, a technique which generates a time-series’ time-dependent spectral decomposition, is modified to develop a new quantitative measure of local dynamical changes and structural breaks. The merit of this integrated technique is demonstrated by analyzing financial data from 1986 to 2012 that includes equity indices, securities and commodities, and foreign exchange. Both procedures successfully detect key historic periods of instability. Moreover, the results reveal distinctions between periods of long-term gradual change in addition to structural breaks. These tools offer new insights into the analysis of financial instability.
