Do Insiders Trade on Government Subsidies?

We examine whether and how insiders trade on government subsidies, a major instrument through which the governments intervene in the economy. Using a novel dataset of government subsidies of Chinese listed firms, we find that net insider purchase increases significantly during the month of subsidy receipt. The effect of subsidies on insider trading is weaker in firms with a more transparent information environment and when subsidies are granted in a more predictable manner. In contrast, the effect is more pronounced for politically connected firms. Further analysis shows that the subsidy-trading relation may reflect both insiders’ informational advantage concerning subsidies and their superior ability to detect mispricing-related opportunities. Our findings provide new insights into the capital market consequences of government subsidies through the lens of insider trading.
