Abstract

This study aims to examine and compare the expenditure and income patterns between traditional market traders in Sukaramai Market and MMTC with street vendors operating around the State University of Medan (UNIMED). This study is based on the main differences between the two groups, especially related to business legality, sales location, and operational costs, which have the potential to affect business effectiveness and the economic welfare of the actors. The comparative quantitative method was used to collect data through questionnaires and Simple Random Sampling sampling techniques on 45 respondents, consisting of 30 market traders and 15 street vendors. The collected data were then analyzed using statistical inference techniques to obtain accurate and reliable parameter estimates. The results of the study show that market traders have an average income of IDR 9.37 million with expenses of IDR 6.7 million per month, so that the net profit obtained reaches IDR 2.67 million. Meanwhile, street vendors have an average income of IDR 7.2 million and expenses of IDR 5.53 million, so that their net profit is around IDR 1.67 million. Although market traders' expenses are higher, they still get a greater net profit. This study confirms that business location, legality, and management system factors significantly affect the efficiency and economic success of traders. This finding is very relevant as a basis for formulating fair and sustainable policies for empowering the informal sector, especially for small and micro traders in urban areas, in order to optimally improve their economic welfare.

Abstract

Since September 2023, Bank Indonesia has activated a triple intervention strategy along with SRBI/SVBI/SUVBI instruments to stabilize the Rupiah amid depreciation pressure exceeding Rp17,000, yet domestic inflation has remained contained — an anomaly at odds with classical exchange rate pass-through (ERPT) theory. This study formally tests whether this ERPT dampening reflects a structural policy-regime shift. Using monthly data for the period January 2017–June 2026, covering the regime before and after BI's active intervention since September 2023 and a Vector Autoregression (VAR) framework, the study applies multi-scale linearity testing, bootstrap placebo tests, Generalized Impulse Response Functions (GIRF), a Threshold VAR (TVAR) as sensitivity analysis, a Nonlinear ARDL-based Error Correction Model for asymmetry testing, and Forecast Error Variance Decomposition (FEVD). Linearity and placebo tests across nine system-threshold combinations consistently fail to reject a linear specification. In the main model, no statistically significant exchange-rate transmission to inflation is found at any horizon (0–12 months); exchange-rate shocks explain only 0.16% of inflation forecast-error variance (FEVD). These findings support the hypothesis that active exchange-rate intervention has dampened the pass-through channel to domestic inflation.
