Does political risk lower bilateral trade flow? A gravity panel framework for Thailand vis-à-vis her trading partners

Abstract

PurposePolitical risk factors play a pivotal role in determining the bilateral trade flow of Asian countries in general and the Association for Southeast Asian Nations (ASEAN) countries in particular. The main purpose of this research paper is to examine the impact of disaggregated political risk in lowering the bilateral trade flow of Thailand, a prominent member of ASEAN, vis-à-vis her 132 trading partners.Design/methodology/approachUsing panel data of Thailand with her partner countries for the period 1984–2015, this paper uses four different panel specifications named pooled ordinary least squares and random effects estimations (estimated generalized least squares estimation) of three types by controlling for cross-sectional heteroscedasticity, time-wise heteroscedasticity and contemporaneous correlation.FindingsHolding other gravity-based determinants constant, for one unit increase in the ranking of indicator of military in politics at home and abroad, trade flow decreases by 5–9% of the total trade flow of Thailand per year. For other types of political risks like government instability at home and abroad, difficulties in investment profile at home and abroad and internal and external conflict at home and abroad, the decrease is also substantial and most statistically significant. The magnitude of loss due to the military channel at home and abroad can amount to US$9.38–US$16.88 bn per year for Thailand, after controlling for other gravity variables.Research limitations/implicationsThe reasons for risk originating from different political channels could be explored at the regional or global level to understand their global and local dimensions.Practical implicationsPolicymakers should attempt to resolve the political risks at home and abroad in an amicable manner, through dialogue, so that bilateral trade flow is not inhibited.Social implicationsBy taking economic reforms only, the trading problem cannot be resolved until and unless Thailand involves her society, politics and administrative mechanisms in a conducive manner to facilitate her trade. A dialogue among bureaucracy, political authority and military is beneficial in mitigating political risks.Originality/valueThe paper is unique in the sense that it makes a solid attempt to identify the potential channels of disaggregated political risk in affecting trade flow negatively, in a gravity framework, by controlling for different kinds of error structure.

The long-run effects of geopolitical risk on foreign exchange markets: evidence from some ASEAN countries

“…The general conclusion that can be drawn from the literature is that political risk and uncertainty/instability is detrimental to growth, development and investor confidence. Goswami and Panthamit (2020) find that increasing political uncertainty lowers trade flows between Thailand and its trade partners. GaoYan (2020) offers evidence that lower political risk in host countries is associated with higher outwards direct investments from China, indicating that political risk affects business decisions in a significant way.…”

A panel path analysis approach to the determinants of coronavirus disease 2019 transmission: does testing matter for confirmed cases?

“…For example, in Gravity literature of International Trade Flow, we use distance between two countries as time-fixed variables, and it is used in the regression. Still, the researchers do not conduct any fixed-effects estimation for these variables (Goswami and Panthamit, 2020). However, we have observed substantial variation across countries, and we are using 212 countries or areas.…”

How geopolitical risk affect firms’ internationalization performance: Evidence from China

“…A large number of literature has provided rich insights into the effects of GPR from both the macro and micro perspectives [ 8 , 9 ]. GPR is an important factor affecting international capital flows [ 10 , 11 ], international trade flows [ 12 , 13 ], asset prices [ 14 ], energy security [ 15 ], sustainable development [ 16 ] and R&D investment [ 17 ]. At the micro-level, there is a growing awareness that the investment strategy choices of multinational corporations are not only related to economic factors but also to GPR [ 18 , 19 ].…”
