Abstract

The paper analyses locations of headquarters of companies and their interactions by inhomogeneous point process, especially local scaling principles, because companies choose their locations according to the number of the local population. Relationships of the companies within economic sectors are studied using the analysis of locally scaled L function. The inhomogeneity was modelled using the local population, then the company’s size was included. Lastly the level of clustering in each sector was computed. The companies are located in three regions in the Czech Republic. It was found out that the companies tend to cluster when the population or the companies’ size is taken into account.

Keywords: Inhomogeneous point process, L-function, Global envelope test, Spatial clusters, Agglomeration

Abstract

The main purpose of the paper is to determine the effect of inflation on total deposits and the financing of sharia commercial banks in Indonesia. A monthly time series data over the period of 2012.1-2017.6 was analyzed using Johansen Co-integration test, vector error correction model, and Granger causality test. The co-integration test indicates that there is a long-run relationship between the variables. In the long-run, inflation is negatively related to total deposits and sharia financing. In the short-run, the inflation has no significant effect on the two variables. The sharia financing has a negative effect on itself at the 1 and 2-month period. The result of the Granger causality test points out that there is a bidirectional causality relationship between total deposits and sharia financing. Furthermore, unidirectional causality running from the inflation to sharia financing and from total deposits to the inflation.

Keywords: Inflation, Total Deposits, Sharia Financing, VECM, and Granger Causality Test

Abstract

The main purposes of our study are to investigate the effect of goods & services spending (GSS) and social spending (SS) on income inequality (GR). Using a panel data set of 26 provinces in Indonesia from 2005 to 2015, panel vector autoregressive and Granger causality test are employed to explore the causal relationship of the variables. The study found out that the SS has a negative and significant effect on GR at the 2-period horizon. The GR has a positive and significant effect on the GSS at the 4-period horizon, but negative and significant effects at the 3-period horizon. The result of the Granger causality test indicates that there is a unidirectional causality running from GSS to SS, and bidirectional causality exists between GR and SS, and between GR and GSS.

Keywords: Income inequality, goods and services spendings, social spendings, Panel Vector Autoregressive, and Granger Causality test.
