Abstract:The notion that more government expenditures can stimulate growth is controversial. The causation between government expenditures and economic growth in Thailand is examined using the Granger causality test. There is no cointegration between government expenditures and economic growth. A unidirectional causality from government expenditures to economic growth exists. However, the causality from economic growth to government expenditures is not observed. Additionally, estimation results from the least square method with lagged variables of economic growth, government expenditures and money supply show the strong positive impact of government spending on economic growth during the period of investigation.JEL Classification: H50; N15; O23

We explore the impact of inflation uncertainty on output growth in Thailand, an emerging market economy with moderate inflation. Inflation and output uncertainty are modeled in a bivariate constant conditional correlation generalized autoregressive conditional heteroskedastic (AR(p)-cccGARCH(1,1)) specification. We include the exchange rate in the mean equations, and use the headline and core inflation rates and industrial production to generate inflation and output uncertainty series. These series are then used in Granger causality tests to make inferences about the effect of monetary policy-induced inflation uncertainty. Causality tests show a positive relation from inflation to inflation uncertainty. Additionally, increased inflation uncertainty decreases output. These results are consistent with real costs associated with moderate inflation. Finally, we find no evidence that monetary policy reduced these costs.a sej_2062 291..308

This paper employ monthly data to examine the empirical relationship between oil price shocks and domestic inflation rate during 1993 and 2013. The results show that oil price, domestic or international, does not have the long-run impact on consumer prices. However, oil price shocks cause inflation to increase while oil price uncertainty does not cause an increase in inflation. Furthermore, inflation itself causes inflation uncertainty. The findings of this study encourage the monetary authorities to formulate a more accommodative policy to respond to oil price shocks.

This study investigates the impact of real exchange rates on the trade balances between Thailand and its major trading partners. Previous empirical evidence gave mixed results of the impact of real exchange rates on trade balances. In this study, Augmented Dicky‐Fuller and Phillips‐Perron tests for stationarity followed by the cointegration tests are implemented. All variables in the model are nonstationary but cointegrated. In cointegrating regressions, biases are introduced by simultaneity and serial correlation in the error. The specification that deals with these problems is the non‐linear specification of Stock and Watson (1989). By using this non‐linear model as modified by Reinhart (1995), the results show that the impact of real exchange rates (Thai baht/foreign currency) on trade balances is significant in most cases. Therefore, the generalized Marshall‐Lerner condition seems to hold. Furthermore, the results show that the real exchange rates play a more important role in the determination of the bilateral trade balances than other factors. Since the real exchange rate variable plays a major role in this study, the policy recommendation is to prevent exchange rate misalignment. A policy that can neutralize the changes in nominal exchange rates and relative prices should be introduced to prevent further deterioration of the trade balance.

This paper provides new evidence on the positive risk-return tradeoff in the Thai stock market using monthly data. An AR(p)-GARCH-in-mean model is applied to the data from January 1981 to December 2009. Since stock prices and dividend series are not cointegrated, the excess returns are separately calculated as capital gain and dividend excess returns. By incorporating the dummy variables that capture the impact of the 1987 global stock market crash and the Asian 1997 financial crisis in the conditional variance equations, the results show that the persistence of excess return volatility is reduced. It is also found that there exists a positive risk-return tradeoff in the stock market in both capital gain and dividend excess returns. The size of the risk-return tradeoff is higher and more highly significant when the market dividend yield is used to obtain the excess return. Therefore, dividend is more important than capital gain. In addition, the impact of volatility on excess returns is not asymmetric implying that the AR(p)-GARCH-in-mean model is sufficient to detect the positive risk-return tradeoff.

This paper explores the validity of the tourism-led growth hypothesis for Thailand using quarterly data during 1995 and 2014. The results from the analysis show that the relationship between tourism receipts and real GDP is nonlinear without asymmetric adjustment. The nonlinearity in this relationship is found from the results of threshold cointegration tests. The causality analysis indicates no causality running from tourism receipts to real GDP in both the long run and the short run. The finding in this paper gives some policy implications.
