### Introduction and background
- During economic crises, developing countries tend to accumulate debt as the growth in expenditure levels exceeds that of revenues while capital inflows decline.
- The mid-2007 global economic crisis had an immense impact on economies throughout the world.
- The current Euro-crisis provides evidence of the effect high debt levels can have on an economy.
- The Caribbean has some of the world’s most indebted nations (as a share of GDP) and accumulated debt from continuous periods of fiscal deficits since the mid-1990s.
- Allowing debt to grow too large can offset positive impacts and lead to problems in the macro-economy, in particular depressing real GDP growth through:
  - Investor expectations of higher future taxes and uncertainty about debt servicing that discourage new domestic and foreign investment.
  - Slower capital-stock accumulation.
  - Lower growth in total factor productivity.
  - Governments being less willing to undertake difficult and costly policy reforms.
- In periods of high debt, policymakers tend to rely on robust economic growth to ensure debt sustainability; when GDP falls, it becomes difficult to raise sufficient revenues to repay debt service obligations.

### Research focus and novelty
- The study investigates countries from only the Caribbean community (CARICOM) to provide a more centered analysis given structural and economic differences across nations.
- Unlike previous research, the study provides a complete view of public debt over various ratios to GDP and its impact on economic growth.
- The paper is positioned as timely given recent global financial turmoil and CARICOM governments’ emphasis on reducing public debt and improving productivity.

### Methodology and data
- Estimation framework:
  - Threshold least square regression model using Hansen (1996, 2000) threshold framework.
  - Model: y_it is real GDP growth; X_it controls include fiscal policy, openness to international trade, inflation, government expenditure, investment, population growth rate, and initial level of GDP per capita; D_it is public debt as a percent of GDP; D* is the debt-to-GDP threshold with indicator I = 1 if debt > D*, 0 otherwise.
  - Fixed effects estimation with cross-section weights to account for country heterogeneity.
  - Time-fixed effects not incorporated due to low degrees of freedom.
  - White cross-section method used to account for cross-equation correlation.
- Threshold search and inference:
  - Threshold search commences at 22 percent and increases by 1 percent up to 110 percent (covers approximately 85 percent of the distribution).
  - Alternate threshold search specified over the range 22 to 112 percent in increments of 0.1 percent (values {22%, 22.1%, 22.2% ... 112%}; total of 900 regressions).
  - Optimal threshold chosen based on standard errors of individual parameters.
  - Hansen bootstrap technique used to simulate the empirical distribution of the likelihood ratio test statistic due to non-standard distributions under the null.
- Data:
  - Annual data 1980 to 2010 for 12 CARICOM countries: Antigua and Barbuda, The Bahamas, Barbados, Dominica, Grenada, Guyana, Jamaica, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Suriname, and Trinidad and Tobago.
  - Variables: public debt, gross domestic product, exports, imports, investment, government expenditure — converted to millions of U.S. dollars and expressed as ratios of nominal GDP.
  - Openness proxied by imports and exports.

### Historical behavior of public debt (selected observations)
- Nominal debt trends 1990–2010:
  - Increasing trends for all 12 selected CARICOM countries; exceptions: Suriname plateau after 1994, Guyana significant fluctuations.
  - Nominal debt levels ranged from U.S$130 million to US$15,055 million for Dominica and Jamaica, respectively.
  - Average debt levels of the Eastern Caribbean Currency Union (ECCU) states and Suriname are markedly less than those of other nations; combined averages ≈ 28 percent of the average debt of Jamaica.
  - Country-specific patterns: Grenada, St. Lucia, Jamaica, Trinidad and Tobago: increases slowed in early and mid 2000s; Antigua and Barbuda, Dominica: decreases in early/mid 2000s.
  - During recessionary years 2008–2010 nominal debt generally continued upward except Antigua and Barbuda (debt restructuring).
- Volatility (standard deviation) of nominal debt:
  - Fixed exchange rate countries to the U.S. dollar (Barbados, Bahamas, and ECCU states): range from US$42 to US$534.
  - Managed floating exchange rate countries: Jamaica US$2900 and Trinidad US$2400.
- Real debt trends:
  - Rising trends for real debt levels excluding Jamaica (Jamaican price level increased much faster than their debt).
- Public debt to GDP ratios:
  - Two distinct bands: debt bands average around 48 percent and 98 percent of nominal GDP.
  - St. Kitts and Nevis: largest debt ratio of 140 percent in 2006, 2007 and 2009.
  - Suriname: minimum of 18 percent in 2008.
  - General pattern: downward trend in latter 1900s and early 2000s, then upward toward end of sample period.
  - All countries except Suriname show a shock to this ratio during 2008–2010.
  - Notably, low volatility for this ratio over the period.
- Average growth in the debt-to-GDP ratio: 6.3 percent.
  - Fastest increase: St. Kitts 12 percent.
  - Lowest: Guyana -2 percent.
  - Growth rate volatility: ranged between a minimum of -39 percent and 54 percent in Suriname and Grenada, respectively.
- Data quality remark: debt variables and ratios exhibit no serious non-normality problems, permitting interpretation of standard errors using the central limit theorem.

### Main findings — thresholds and debt-growth relationship
- Identified threshold impacts at 30 percent and 56 percent of debt-to-GDP (Figures 5–9); threshold estimation from Equation (2) yields a threshold value of 54.7 percent (Table 5).
- Bootstrap significance:
  - Threshold estimate p-value = 0.002.
- Interpretation of thresholds and coefficients:
  - When debt < 30 percent of GDP: increases in debt-to-GDP up to the threshold are associated with faster economic growth of roughly 0.41 percentage points (average of debt coefficients between 22 and 29 percent).
  - When debt > 30 percent but below the higher threshold: positive effect on growth is much smaller and statistically insignificant.
  - At around 56 percent of GDP: growth effects switch from positive to negative; debt becomes a drag on growth.
  - With threshold D* = 54.7 percent: coefficient γ1 positive and significant; coefficient γ2 negative and significant.
  - If debt exceeds 54.7 percent, each additional percentage point in public debt-to-GDP costs approximately 0.08 percentage points in annual average economic growth.

### Selected estimation results (Table 5)
- Least Square estimates:
  - γ1 = 0.127 (p-value 0.051)
  - γ2 = -0.082 (p-value 0.015)
  - Initial GDP per capita = -0.159 (p-value 0.052)
  - Openness = 0.004 (p-value 0.139)
  - Inflation = -0.003 (p-value 0.071)
  - Investment to GDP(%) = 0.06 (p-value 0.017)
  - Government Expenditure to GDP (%) = -0.126 (p-value 0.036)
  - D* = 54.7
  - R-squared = 0.457
- Two-Stage LS (instruments, first lags):
  - γ1 = 0.123 (p-value 0.072)
  - γ2 = -0.080 (p-value 0.000)
  - Initial GDP per capita = -0.176 (p-value 0.008)
  - Openness = 0.004 (p-value 0.139)
  - Inflation = -0.003 (p-value 0.070)
  - Investment to GDP(%) = 0.053 (p-value 0.002)
  - Government Expenditure to GDP (%) = -0.146 (p-value 0.001)
  - D* = 55.8
  - R-squared = 0.448

### Channels and additional thresholds by variable
- Investment:
  - Debt < 30 percent of GDP: investment has a positive and significant impact on growth.
  - Debt > 30 percent: positive investment effect diminishes and becomes statistically insignificant.
- Trade openness:
  - Tipping point at debt = 34 percent of GDP.
  - Debt < 34 percent: greater openness to trade has a positive impact on growth.
  - Debt > 34 percent: trade effects on growth are insignificant.
- Government expenditure:
  - Negative impact on growth becomes significant once debt exceeds 47 percent of GDP.
  - Beyond 47 percent: every 10 percentage points increase in the debt ratio slows growth, via the government spending channel, by an average of 0.4 percentage points.
- Inflation:
  - Impact on growth depends on the 47 percent threshold.
  - Debt < 47 percent: inflation has a negative impact on growth.
  - Debt > 47 percent: inflation effects on growth are insignificant.

### Country-level estimated losses (Table 6)
- Annual percentage point loss in real GDP growth and cumulated loss since 1980 (in percentage points of real GDP growth):
  - Antigua and Barbuda: 3.31 ; 102.59
  - The Bahamas: n/a ; n/a
  - Barbados: 1.65 ; 32.98
  - Dominica: 1.12 ; 23.38
  - Grenada: 1.59 ; 25.37
  - Guyana: 16.76 ; 519.70
  - Jamaica: 5.22 ; 161.97
  - St. Kitts and Nevis: 5.46 ; 76.46
  - St. Lucia: 0.51 ; 4.62
  - St. Vincent: 0.37 ; 5.50
  - Suriname: 53.74 ; 322.43
  - Trinidad and Tobago: 0.42 ; 6.26
- Example interpretation:
  - Barbados: public debt rose above the threshold in 1991 and reached roughly 129 percent of GDP in 2010, costing approximately 1.65 percentage points in real GDP growth per annum, equivalent to 32.98 percentage points loss over the 1991–2010 period.

### Robustness and endogeneity checks
- Re-estimation via two-stage least squares with first lags as instruments:
  - Resulting threshold = 55.8 percent of GDP.
  - Estimates similar to least squares results.
  - Sum of squared residuals depicted in Figure 11.
- Hansen bootstrap technique applied for inference; threshold estimate p-value = 0.002.

### Conclusion and policy recommendations
- Summary conclusions:
  - Debt contributes positively to growth when below 30 percent of GDP.
  - Debt becomes a main concern for output beyond 55 percent of GDP.
  - Between 30 and 55 percent of GDP the marginal impact of debt diminishes; above ~55 percent it turns negative.
- Policy implications and recommendations:
  - Countries with debt ratios above 55 percent should aim to achieve debt-to-GDP levels that do not impede growth by adopting policies that put debt on a trajectory towards the 55 percent threshold.
  - Governments should target debt levels well below estimated thresholds to allow buffer space for recessionary periods or shocks such as natural disasters.
  - Fiscal consolidation is critical for countries with high debt-to-GDP ratios but may be difficult amid slow recovery and higher unemployment.
  - Complementary strategies suggested:
    - Improve trade through CARICOM or the Caribbean Single Market and Economy (CSME) to realize cost savings and scale economies (for example, integrating financial supervision and regulation).
    - Advance information technology and renewable energy production to reduce oil import bills (region is net importer of oil products except Trinidad and Tobago) and provide better incentives for renewable energy usage.
- Comparative context:
  - A much lower threshold was found for the Caribbean region compared to Reinhart and Rogoff (2010) and Caner et al. (2010), attributed to small size and lack of physical resources (excludes Jamaica and Trinidad and Tobago), heavy reliance on tourism, and underdeveloped capital markets making economies more vulnerable to external shocks.

### Research focus and novelty
- The study investigates countries from only the Caribbean community (CARICOM) to provide a more centered analysis given structural and economic differences across nations.
- Unlike previous research, the study provides a complete view of public debt over various ratios to GDP and its impact on economic growth.
- The paper is positioned as timely given recent global financial turmoil and CARICOM governments’ emphasis on reducing public debt and improving productivity.

### Literature context
- Earlier literature used predominantly causality approaches (Scott, 1995; Amoateng and Amoako-Adu, 1996; Karagol, 2002).
- Recent studies have sought threshold levels for the debt-to-GDP ratio:
  - Reinhart and Rogoff (2010) alluded to debt ratios beyond 90 percent as detrimental to economic improvement.
  - Caner et al. (2010) proposed a threshold of 77 percent.
- Prior studies combined developed and developing countries across regions and did not concentrate on a single geographical area.

### Methodology
- The paper employs the threshold estimation technique outlined by Hansen (1996, 2000).
- In addition, a new regression approach is utilised and adapted to a growth model specifically designed for the Caribbean community.
- The new method allows assessment of the impact of public debt on economic growth as the debt-to-GDP ratios vary over a pre specified range, providing a relatively complete view of public debt ratios dynamics on economic growth and other determinants.

### Key findings and estimated thresholds
- The findings suggested a debt threshold of about 56 percent of GDP.
- The study showed that debt under 30 percent of GDP is beneficial for the economies.

### Policy implications and relevance
- Policymakers such as central bankers, regulators, and supervisors can better understand the role of debt in the economy and identify when debt begins to get too excessive.
- The analysis is intended to inform CARICOM policy-makers aiming to reduce debt levels and improve productivity in the wake of global financial stresses.

### II. THE HISTORICAL BEHAVIOR OF PUBLIC DEBT
- Increasing trends in nominal debts observed for all 12 selected CARICOM countries during 1990 to 2010; exceptions:
  - Suriname: debt level plateau after 1994.
  - Guyana: significant fluctuations.
- Nominal debt levels ranged from U.S$130 million to US$15,055 million for Dominica and Jamaica, respectively.
- Average debt levels of the Eastern Caribbean Currency Union (ECCU) states and Suriname are markedly less than those of other nations; combined averages ≈ 28 percent of the average debt of Jamaica.
- Country-specific nominal debt observations:
  - Grenada, St. Lucia, Jamaica, Trinidad and Tobago: increases slowed in early and mid 2000s.
  - Antigua and Barbuda, Dominica: decreases observed in early/mid 2000s.
  - During recessionary years 2008–2010 nominal debt generally continued upward except Antigua and Barbuda (debt restructuring).
- Volatility (standard deviation) of nominal debt:
  - Fixed exchange rate countries to the U.S. dollar (Barbados, Bahamas, and ECCU states): range from US$42 to US$534.
  - Managed floating exchange rate countries: Jamaica US$2900 and Trinidad US$2400.
- Real debt trends:
  - Rising trends exist for real debt levels excluding Jamaica (Jamaican price level increased much faster than their debt).
- Public debt to GDP ratios present in two distinct bands:
  - Debt bands average around 48 percent and 98 percent of nominal GDP.
  - St. Kitts and Nevis: largest debt ratio of 140 percent in 2006, 2007 and 2009.
  - Suriname: minimum of 18 percent in 2008.
  - General pattern: downward trend in latter 1900s and early 2000s, then upward toward end of sample period.
  - All countries except Suriname show a shock to this ratio during 2008–2010.
  - Notably, low volatility for this ratio over the period.
- Average growth in the debt-to-GDP ratio: 6.3 percent.
  - Fastest increase: St. Kitts 12 percent.
  - Lowest: Guyana -2 percent.
  - Growth rate volatility: ranged between a minimum of -39 percent and 54 percent in Suriname and Grenada, respectively.
- Data quality remark: debt variables and ratios exhibit no serious non-normality problems, permitting interpretation of standard errors using the central limit theorem.

### III. LITERATURE REVIEW (select findings and thresholds reported)
- Theoretical channels for nonlinear relationship between debt and growth include: private savings, public investment, total factor productivity, interest rates, inflation, and capital accumulation; investment is emphasized.
- Debt overhang and liquidity/budget constraint hypotheses provide mechanisms for growth-reducing effects of high debt.
- Empirical approaches to prudential debt limits: histograms, spline functions, threshold estimations.
- Reported thresholds from literature (exact values as presented):
  - Reinhart and Rogoff (2010): tipping point of 90 percent of central government debt to GDP; 60 percent for external debt (government plus private) for emerging market economies.
  - Caner et al. (2010) (Hansen threshold technique): average threshold 77 percent for public debt to GDP (developed and developing), 64 percent for emerging markets alone.
  - Cordella et al. (2005): tipping points between 15–30 percent for countries with good policies and institutions (non-HIPCs), and 0-20 percent for economies without HIPCs.
  - Pattillo et al. (2002): external debt impact becomes negative above 35–40 percent of GDP; marginal effect negative at about half these levels.
  - Clements et al. (2003): threshold ≈ 50 percent nominal external debt to GDP; 20–25 percent for net present value of external debt to GDP.
  - Boamah and Moore (2009): external debt positively related to growth in good policy environment but growth-reducing above threshold of 63 percent.
  - IMF (2003) fiscal reaction and benchmark analyses:
    - Primary balance response stops when debt surpasses 50 percent of GDP for emerging economies, 80 percent for industrial countries.
    - Benchmark debt-to-GDP ratio found to be 25 percent for emerging markets and 75 percent for industrial economies.
- Other approaches to identifying debt thresholds include external balance impacts, fiscal policy efficacy at various debt levels, and debt intolerance regressions using credit ratings.

### IV. METHODOLOGY AND DATA (model and estimation approach)
- Threshold least square regression model specified as:
  - y_it is real GDP growth.
  - X_it is matrix of controls: fiscal policy, openness to international trade, inflation, government expenditure, investment, population growth rate, and initial level of GDP per capita.
  - D_it is public debt as a percent of GDP.
  - D* is the debt-to-GDP threshold; indicator function )(*
DD

 used.
- Estimation details and identification choices:
  - Fixed effects estimation with cross-section weights to account for country heterogeneity.
  - Time-fixed effects not incorporated due to low degrees of freedom.
  - White cross-section method used to account for cross-equation correlation.
