Impact of COVID-19 on Remittance Inflows to Samoa

The COVID-19 pandemic, which has affected many countries since January 2020, has created large-scale contractions of economies globally (International Monetary Fund, 2020). The more the pandemic affects economic growth and employment prospects in developed countries, the greater will be the effects on low income, developing countries. An immediate loss is predicted to be through reduced remittance inflows from developed countries (Sayeh & Chami, 2020). World Bank (2020) projects a 20 percent decline in remittances and a loss of $445 billion in remittances to low and middle-income countries due to loss of income and employment of migrant workers. Several studies note a significant reduction in remittances due to COVID-19 in Africa (Bisong et al., 2020), the Philippines (Ang & Opiniano, 2020; Murakami et al., 2020) and Bangladesh (Das, 2020). A significant loss of remittances will have a profound impact on household’s social protection net and progression of sustainable development goals. This paper investigates the effect of COVID-19 on remittance inflows to Samoa from three major remittance sending countries, namely Australia, New Zealand, and the United States. The case of Samoa is interesting since remittances represent around 20 percent of its GDP and it is the sixth largest remittance receiving country (Gaillard & Friesen, 2015; World Trade Organization, 2019). Moreover, remittances reached around 40 percent of all households in Samoa, making up a significant portion of family income (AusAID, 2012). Since remittances in Samoa are a major contributor to economic output and household income, the effect of external shocks, such as the COVID-19 pandemic, could have severe implications. Previously, economic and disaster shocks had mixed effects on Samoa’s remittance inflows. Remittances were 3.6 times higher during the 2009 tsunami compared to a normal year (Le De et al., 2016) while remittances declined during the 2009 global financial crisis as a result of laid-off Samoan migrants (AusAID, 2012). In this paper, we examine the determinants of remittance inflows to Samoa. In light of the discussion above, which points towards a significant decline in remittances due to the COVID-19 pandemic, our hypothesis is that COVID-19 has negatively impacted remittance inflows to Samoa. We test this hypothesis using a cointegration and vector error correction framework. We find that COVID-19 has led to increased remittances to Samoa from Australian and New Zealand, while remittances from the United States have declined. This finding contributes to the scarce literature (Ang & Opiniano, 2020; Bisong et al., 2020; Das, 2020; Murakami et al., 2020) on the effects of COVID-19 on remittances. By studying a country, Samoa, which is the 5th largest recipient of remittance, we set the framework and motivation for more analysis building on our work. The rest of the paper is structured as follows: Section II provides the methodology and data. Section III discusses the empirical findings and Section IV concludes and provides policy implications.


I. Introduction I. Introduction
The COVID-19 pandemic, which has affected many countries since January 2020, has created large-scale contractions of economies globally (International Monetary Fund, 2020). The more the pandemic affects economic growth and employment prospects in developed countries, the greater will be the effects on low income, developing countries. An immediate loss is predicted to be through reduced remittance inflows from developed countries (Sayeh & Chami, 2020). World Bank (2020) projects a 20 percent decline in remittances and a loss of $445 billion in remittances to low and middle-income countries due to loss of income and employment of migrant workers. Several studies note a significant reduction in remittances due to COVID-19 in Africa (Bisong et al., 2020), the Philippines (Ang & Opiniano, 2020;Murakami et al., 2020) and Bangladesh (Das, 2020). A significant loss of remittances will have a profound impact on household's social protection net and progression of sustainable development goals. This paper investigates the effect of COVID-19 on remittance inflows to Samoa from three major remittance sending countries, namely Australia, New Zealand, and the United States. The case of Samoa is interesting since remittances represent around 20 percent of its GDP and it is the sixth largest remittance receiving country (Gaillard & Friesen, 2015;World Trade Organization, 2019). Moreover, remittances reached around 40 percent of all households in Samoa, making up a significant portion of family income (AusAID, 2012). Since remittances in Samoa are a major contributor to economic output and household income, the effect of external shocks, such as the COVID-19 pandemic, could have severe implications. Previously, economic and disaster shocks had mixed effects on Samoa's remittance inflows. Remittances were 3.6 times higher during the 2009 tsunami compared to a normal year (Le De et al., 2016) while remittances declined during the 2009 global financial crisis as a result of laid-off Samoan migrants (AusAID, 2012).
In this paper, we examine the determinants of remittance inflows to Samoa. In light of the discussion above, which points towards a significant decline in remittances due to the COVID-19 pandemic, our hypothesis is that COVID-19 has negatively impacted remittance inflows to Samoa. We test this hypothesis using a cointegration and vector error correction framework. We find that COVID-19 has led to increased remittances to Samoa from Australian and New Zealand, while remittances from the United States have declined. This finding contributes to the scarce literature (Ang & Opiniano, 2020;Bisong et al., 2020;Das, 2020;Murakami et al., 2020) on the effects of COVID-19 on remittances. By studying a country, Samoa, which is the 5 th largest recipient of remittance, we set the framework and motivation for more analysis building on our work.

II. Methodology, Data, and Preliminary Observations II. Methodology, Data, and Preliminary Observations
The effects of the COVID-19 pandemic on remittance inflows are tested within a vector error correction (VECM) model: is each variable covered in the model, including and a vector of variables ; is the first difference of each variable; is the natural logarithm of remittances from either Australia, New Zealand or the United States to Samoa (US$, current prices); and is a classical error term. The , , and are parameters to be estimated. The parameter, , captures the error correcting term ( ) and measures the speed at which the model returns to equilibrium after a shock. The parameter, , captures the long-run equilibrium relationship between and . The parameter, , captures the constant term in the shortrun relationships, and captures short-run dynamic effects of changes in all variables stated in Equation (1).
The vector includes the COVID-19 pandemic variables of interest, represented by three indicators. (1) a dummy variable, denoted by , with value 1 for months March 2020 onwards, and 0 otherwise. This is based on the period when deaths from the pandemic began. The starting month when first deaths from the pandemic were recorded is the same in Australia, New Zealand and the United States. (2) the number of confirmed COVID-19 cases per million population, denoted by .
(3) the number of deaths caused by COVID-19 per million population, denoted by . The control variables in the vector include factors of the following dimensions: 2 (1) economic performance of remittance originating country, represented either by unemployment rate in percentage (denoted by ) or by the industrial production index (denoted by ); (2) exchange rate, represented by Samoan Tala per origin country's currency (denoted by ); and (3) the cost of sending remittance in the United States dollars (natural logarithm, denoted by ). In this study, we utilize monthly data from May 2012 to July 2020. A prior look at remittance inflows trend in Figure 1 shows remittances from Australia and New Zealand have an increasing trend from January 2020 while it declined for the United States. We obtained the remittances inflow, monthly cost and exchange rate indicators from the Central Bank of Samoa while the unemployment rate, interbank rate and industrial production indexes ( ) are sourced from the Federal Reserve Economic Data. The was transformed from quarterly to monthly frequency through using cubic spline interpolation. Another control variable, which is available at the monthly frequency and relevant according to the literature on the determinants of remittances considered in this study is interbank rate. However, due to its high correlation with the two economic performance indicators, industry production index and unemployment, interbank rate is excluded from the regressions.   This table reports results from the estimation of regression model (1). The dependent variable is remittance inflows . The z-statistics are in parentheses below parameters; * ( ** ) *** denote statistical significance at the 10% (5%) 1% levels. Columns (1)-(3) are regressions for remittance inflows from Australia to Samoa, columns (4)-(6) are regressions for remittance inflows from New Zealand to Samoa, and columns (7)-(9) are regressions for remittance inflows from the United States to Samoa.

III. Empirical Results
The VECM regression results are summarized in Table  1. 3 The long-run equilibrium relationships are reported in the top panel of Table 1. For short-run dynamic relationships, to conserve space, only dynamic effects of each pandemic indicator on are reported in the bottom panel of Table 1. As the lagged residual has a negative and statistically significant sign in all regressions, except for column (8), there is strong evidence of a longrun equilibrium causal effects of control variables and the COVID-19 pandemic on remittances to Samoa. Exchange rate plays a significant role in promoting remittance inflows from Australia to Samoa only. The cost of sending remittances negatively affects remittance inflows from New Zealand and the United States, which does not hold for remittances from Australia. Economic performance is found to be contributing positively to remittance inflows to Samoa, with the evidence of a negative association between unemployment rate and remittance inflow from Australia and New Zealand and a positive association between industrial production index in the United States and remittance inflows to Samoa. There is strong evidence that the COVID-19 pandemic effects in Australia and New Zealand have contributed to more remittance flows to Samoa from these two countries, while, it has negatively influenced remittance inflows from the United States. The short-term effects of COVID-19 on remittances to Samoa are country sensitive. It is found that the pandemic leads to short-term reduction of remittances from Australia and New Zealand to Samoa.

IV. Conclusion IV. Conclusion
This study examined the impact of COVID-19 on Samoa's remittance inflows from Australia, New Zealand and the United States. The study finds strong evidence that the pandemic positively affects long-term remittance inflows to Samoa from Australia and New Zealand, which contradicts prior studies, such as Murakami et al. (2020) that concluded a negative relationship. On the other hand, remittances to Samoa from the United States is negatively impacted by the pandemic. Cultural collectivism and strong family links in Samoa could explain the higher remittance inflows to support the home-based family members. Also, the effects of the pandemic have been far more serious in the United States in terms of cases and deaths compared to Australia and New Zealand. Given the strong cultural and social links between the Pacific Island countries and Australia and New Zealand, the remittance support for Pacific Islanders is likely to stay strong during the pandemic. To save space, only the ECM's parameters and short-run effects of COVID-19 variables in individual regressions are reported.
