Does Buying Local Spur Corporate Investment? (New Draft Coming Soon)
Motivated by political incentives, governments may give preferential treatment to suppliers that are their political constituents. In addition, it's unclear if politically incentivized purchases result in more corporate investment or not. To answer the two questions, I construct a novel and granular data set of the purchases of 308 councils in England with corporate suppliers in monthly frequency from 2011 to 2020. First, I document that compared to non-local councils, suppliers receive more specialized contracts from the local council and maintain a more persistent customer-supplier relationship with it. Next, to identify the causal relationship between local sales and suppliers’ outcomes, I exploit exogenous demand shocks jointly with spatial fixed effects on the councils’ boundaries. I find that local sales reduce the uncertainty of firms’ cash flows while keeping expected cash flows unchanged. It implies that the customer-supplier relationship with the local council is not only more persistent but also more exclusive. Consequently, I find local sales result in 9.7% higher annual growth in fixed assets than sales to non-local sales. The results suggest that the reduction in uncertainty provides the main explanation for the positive impacts of politically incentivized purchases on investment. Overall, this paper highlights novel patterns of governments’ favoritism towards local suppliers via differentiation in contract terms and such demand-side characteristics do shape firms’ behaviors in multiple dimensions.
Most research on venture capital (VC) focuses on VCs’ value-add to their portfolio companies. Weexplore the value-add of VCs beyond their portfolios, specifically as a by-product of their due diligence.We hypothesize that VCs’ due diligence helps entrepreneurs mitigate information frictions. We test this hypothesis using data on nearly 2,000 applicants for funding to a seed Fund that screens them for due diligence by quasi-randomly assigning their applications to reviewers. We find that assignment to the Fund’s due diligence leads to higher growth, potentially by mitigating information frictions internal to the entrepreneur rather than via signaling or networking effects。
Does the quality of government have real effects on economic activities? I provide micro evidence from the housing market and firms’ borrowing behaviours in London. I focus on a single-dimension and verifiable task of bureaucrats—the permission for development plans of new buildings or house renovations to measure the quality of government. Using a hand-collected dataset of over 2.2 million planning applications from 2000 to 2020 in London, I show there is a causal and positive relationship between the speed of the application approval and the trading and value of both residential and commercial properties. Firms that own properties in London increase their chance of creating collateralized loans when exposed to faster planning approval. The effects arise because the timing of property development is important to households and firms. The delay in planning permission will lead them to abandon the project and change behaviours in housing markets and borrowing.
