Abstract
This study analyzes the relationship between four types of economic crises and four poverty indices in an effort to determine which type of crisis most affects the poor, and find possible solutions. This study is particularly concerned with Latin American countries in which International Monetary Fund bailout programs have failed due to repeated crises, longer lasting inflation, and most of all poverty. The results indicate an apparent worsening trend in poverty measures due to the crises. Among several types of crises, debt crisis and currency crisis play larger roles than others, particularly with the headcount poverty ratio US$3.10.
Introduction
Crisis impedes economic activity, undermining the consumption levels and lowering the demand for investments. Depressed economic activity leads to lower growth rates, higher unemployment rates, and lower wages, which eventually has a negative impact on the individual standard of living. Do crises seriously affect a country’s poverty level? If so, which type of crisis plays major roles and how can the effects be mitigated? Hopkins (2006) examined the relationship between crisis and health in three countries – Indonesia, Malaysia, and Thailand – and found that economic crisis led to a decline in real household income and government tax revenue, which diminished access to high quality food, health facilities, and education. A number of other studies have examined a variety of countries – Suryahadi and Sumarto (2003), Dhanani and Islam (2002), and Manning (2000) on Indonesia; Lokshin and Ravallion (2000) on Russia; Ahmed and O’Donoghue (2010) on Pakistan, and Breisinger et al. (2011) on Yemen.
Latin America is of particular importance in this study; it has suffered from repeated crises (see Table 1 for the list of countries and the crises they had experienced), unstable macroeconomic conditions (see Table 2 for government debt stock), long lasting hyper-inflation (see Table 3 for inflation and consumer price), and unsuccessful domestic monetary and fiscal policies, as well as unsuccessful bailout packages from the International Monetary Fund (IMF). Moreover, the region is closely associated with the United States – geographically, politically, and economically – which makes the region vulnerable to shocks stemming from the world’s largest economy. Against this backdrop, several studies have investigated the impact of crisis on Latin American countries. Ocampo (2009) focused on the impact of “transmission of crisis” – remittance, trade, and banking – on several economic factors and found that all 18 Latin American countries had experienced a decrease in current account balance, with the biggest drop in Chile, up to 7.4%, during the 2007–2008 period. Nikoloski (2011) examined the impact of currency, banking, and debt crisis on poverty measures and found the currency crisis is related with a higher “level” of poverty while the banking crisis explains the higher “depth” of poverty. Ocampo (2009) examined the theoretical connection between economic crisis and the poverty indicator, and Laeven and Valencia (2008, 2012) provided empirical evidences for selecting explanatory variables in terms of the government sector, external factors, and economic conditions.

This study revisits the findings from the above-mentioned studies with improved methods and up-to-date dataset. 1 In addition, this study breaks down crises (global crises, banking crises, currency crises, and debt crises), and poverty indicators (poverty gap measures and poverty headcount ratios with two indicators: US$1.90 a day and US$3.10 a day) into different types. The dataset used in this study is panel data that covers 17 Latin American countries between 1990 and 2013, which is by far the most-up-to date dataset in the literature. The methods used in this study are based on Hopkins (2006) and Nikoloski (2011) but are different from theirs because of the amended poverty indicators and the addition of global crisis as a dummy variable to investigate how the US-originated economic crisis in 2007 affected Latin American countries.
This study is of particular importance given that, although economic growth 2 is an important factor reducing a country’s poverty level, such link does not work in Latin American countries; economic growth of the several economies since the 2000s has little impact on reducing poverty and households with chronic poverty were unable to escape from poverty solely through economic growth (Vakis et al., 2016). Among many contributing factors, repeated economic crises in the region may be an important stumbling block. More specifically, economic crises cause aggregate demand to fall, and the relative price to change dramatically. This affects labor markets unfavorably, which decrease the demand in the labor markets and eventually decrease the real wage of workers (ILO 2017). Another important factor is the default in the financial system due to crises, which prevent the poor from accessing financial systems and they end up using the informal financial sector, which makes them even more vulnerable due to higher interest rate and reserve requirement (Gelos, 2009).
Data, methods, and models
This study covers 17 Latin American countries that have experienced at least one economic crisis between 1990 and 2013 (see Table 1 for the list of those countries). “Crisis” in this study is categorized into four different parts – banking, currency, debt, and global crisis – all of which have intrinsic links to poverty, as shown in Ocampo (2009) and Nikoloski (2011). Banking crisis is defined as the reduction in the value of the asset which often leads to bank closure, then government control over the financial system, which deteriorates the value of deposit and asset of the low-income family, which hinders the poor to access formal financial systems. Currency crisis is defined as the fluctuation in the exchange rate, foreign exchange reserve or short-term interest rates (Sharma, 1999), which not only influences the sharp decline in growth but also shifts the composition of the labor market, leading to the poor to work in low-quality employment (Nikoloski, 2011). Third, the debt crisis is defined as defaults on bank loans or bond spread above the critical level (Pescatori and Sy, 2007), which has a direct impact on government spending and lessens the investment in the social safety net. Lastly, a global crisis is defined as declined economic activity mainly due to external factors, such as trade shocks, which increases domestically the living cost of the low income group which is international financial linkage (Lane and Milesi-Ferretti, 2011; Ocampo, 2009).
The dependent variables in this study are four poverty indicators – two measurements (poverty gap 3 and the component of the population considered to be poor) and two criteria (US$1.90 and US$3.10). The two different poverty lines are used in this study due to the sample heterogeneity; Brazil’s per capita GDP is much higher than that of Nicaragua, so it would be better to apply US$3.10 to Brazil and US$1.90 to Nigaragua to effectively measure the poverty level. The data source is the World Bank’s World Development Indicator and is primarily based on household survey data. Unlike the poverty gap that measures “depth” of poverty, headcount ratio simply measures the percentage of population under a certain poverty line (either US$1.90 or US$3.10 per day, with base year 2011).
The independent variables include four dummy variables for the economic crisis (banking, currency, debt, and global 4 ), the initial macroeconomic condition, the percentage of foreign banks among total banks, bank deposit or national debt to GDP (Table 2), inflation and consumer price index (Table 3), trade as the percentage of GDP (Table 4), and general government final consumption expenditure. The regression equation is as follows
where
PovGap1.90: income or consumption gap under the poverty line of US$1.90 a day
PovGap3.10: income or consumption gap under the poverty line of US$3.10 a day
HeadPov1.90: the percentage of the population that lives under the US$1.90 a day
HeadPov3.10: the percentage of the population that lives under the US$3.10 a day

Summary of descriptive statistics for each variable is provided in Table 5. Countries that did not go through any economic crisis at least once between 1990 and 2013 were excluded. In addition, due to the short data availability, data points before the year 1990 were not included. Since the poverty gap measure and the poverty headcount indicator are derived from income criteria, the multi-dimensional poverty perspective was not included. Other views, such as child mortality, nutrition intake, years of schooling, and child school attendance are excluded in income base poverty indicators. Moreover, housing-related factors such as availability of electricity, drinking water, sanitation, flooring, cooking fuel, and assets are also excluded.
Summary of descriptive statistics.
As for the methods, this study adopts fixed effect (within transformation) panel analyses based on the Hausman test, stating that the fixed effect estimation is systematically different from random effect estimation, in which case, fixed effect provides consistent estimation results and overcome potential endogeneity problems.
Results
Table 6 shows the results for banking crisis. The coefficient for the banking crisis dummy is consistently positive for all the models (whether dependent variable is headcount ratio or poverty gap), implying that the banking crisis indeed exacerbates the poverty problem. Model 1-4, which uses headcount index US$3.10 a day, shows the largest coefficient of 4.482, stating that a banking crisis will increase the number of people living under this poverty line by 4.5%. In Model 1-1 where poverty gap of US$1.90 a day has been used as the dependent variable, the coefficient is 1.098, meaning that, when banking crisis occurs the gap between poverty line of US$1.90 a day and the lowest income group’s living cost becomes US$1.098 a day, which means the lowest income group in an economy would live with only US$0.802 a day. As for the other independent variables, logged GDP is significantly negative throughout all the models.

Table 7 explains currency crisis dummy. The poverty gap of US$1.90 a day did not provide any significant coefficient (the results have not been included in this table, though), and for this reason, this table focuses more on using the headcount ratio (four out of five models). The significantly positive signs shows distinctive worsening trends of poverty index when the currency crisis occurs, with larger coefficient than the case of banking crisis; the largest one is 8.437 in Model 2-5, which is large enough to take a number of population trapped in extremely poverty. As for the other variables, the coefficient for the logged GDP is significantly negative, while government spending, inflation, deposit, and foreign bank ratio do not show any significance with small values.

Tables 8 and 9 are about debt crisis and global crisis, respectively. Models 3-1 to 3-5 in Table 8 reveal that debt crisis does worsen the poverty. The effect is particularly large in Model 3-5 where US$3.10 has been used as a headcount poverty line – the coefficient for the dummy variable is as high as 8.952. The models in Table 9 provide interesting results for the global crisis dummy, which is negative. This unexpected result can be interpreted in several ways. For one reason, as the names tell, the global crisis was not originated domestically in Latin America but mixed with other economic factors, interpreting the link quite complicatedly; for example, before the external factors come into play in Latin American countries, they could have been able to cope with them with relevant policies, in which the actual poverty level in the region could have decreased. Other independent variables, however, have the same results as the previous ones.

Last, but not least, clustered standard error and correlation among dummy variables have been checked and to confirm there would be no multi-collinearity issue (see Table 10).

Conclusion
Many Latin American countries went through the so-called “lost decade,” with net external borrowing having skyrocketed and account deficits, as well as the trade deficits leading to debt accumulation and higher interest rates (Pastor, 1989). This may explain the significantly positive coefficients in debt crisis, larger than any other crisis dummies. Currency crisis also turned out to be an important factor while the banking crisis is not as crucial as expected. Global crisis brought unexpected results, which could be explained by several other factors tangled with it. Among other independent variables, the log GDP seems to be meaningful and significant throughout all the models.
After describing the impact of crises on poverty indicators, the next question should be how a country can recover from the poverty. This is particularly important in Latin America, as several IMF bailout package packages failed to be solutions and many countries had suffered from chronic and repeated crises. The adverse external conditions and the high poverty rate raised the cost of the IMF program implementation, which caused a high number of program cancellations and the countries resorted once again to IMF programs (Hutchison and Noy, 2003). Examining how to break this vicious cycle should be a very important and relevant follow-up topic, which is going to be reserved for further studies.
