Abstract

This paper examines the robustness of the ADF (Augmented Dickey-Fuller) unit root test to the presence of one structural break. The ADF test results show one variables out of six to be stationary. To check their robustness, two separate additive outlier (AO) models are employed: one allowing for one endogenously-determined break in the intercept and the other in the trend. These two tests can not reject the unit root null hypothesis for all the vari-ables. However, when an innovational outlier (IO) model, that allows for one endogenously-determined break is estimated, the null hypothesis can be rejected for 3 more series. The estimated break dates mostly correspond to the 1998 financial crisis in Indonesia.Keywords: unit root; stationarity; structural break, additive & innovational outlierJEL classification: C1; C22

Abstract

This paper tests whether the bank lending channel works in Indonesia. It develops an errorcorrection representation of the Autoregressive Distributed Lag (ARDL) model of two bankcredit markets. Each model takes account of one structural break associated with the 1998financial crisis. The date of the crisis is determined by a unit root test that includes twostructural breaks. Instead of Johansen’s cointegrating procedure, bounds test procedure isimplemented. The estimated error correction model for both markets suggests that bankloans adjust more strongly towards loan supply, implying that monetary-induced disturbancesin bank loans originate from the supply side.Keywords: bank lending channel, unit root, structural breaks

Abstract

Indonesia has been developing various sectors of its economy, and so it needs a huge amount of capital. Therefore, it has been putting a lot of efforts to develop its capital market. This paper analyzes the impacts of domestic and foreign factors on Indonesia stock price. Some considered domestic factors are interest rates, production index, and foreign exchange rates. Various considered foreign factors are Singapore and US stock prices. The paper uses Vector Error Correction Mechanism model to analyze the data. The estimation results suggest that all variables significantly influence Indonesia stock price, with Singapore stock price as the dominant factors.Keywords: Stock price, interest rates, exchange rates, production indexJEL classification numbers: G12, G15
