I use a natural experiment in 1980s Japan to provide evidence of the feedback loop between corporate borrowing and commercial property investment emphasized in macro-finance models with collateral constraints. Following national land use deregulations, firms located in previously land use constrained areas borrowed and invested more in real estate, reinforcing the initial positive shock to land values. I develop a multi-city spatial model with real estate collateral which uses reduced form estimates of the deregulation on firm outcomes to assess aggregate policy effects. The deregulation and corporate borrowing frictions together amplified the aggregate cycle and promoted growth in superstar cities.

Housing affordability concerns have led policymakers worldwide to consider transfer taxes targeting speculators. We estimate optimal taxes on property flips using a heterogeneous investor model which extends the intuition for imposing financial transaction taxes, or Tobin taxes, to the housing market. Our framework incorporates investors’ housing tenure choice, search costs, and heterogeneity in investment horizon. We calibrate the model using responses to a 2011 Taiwan sales surcharge levied on investment properties flipped within two years. Linking the universe of income tax returns to transaction records, we show the tax generated a 40% drop in second home sales volume. The resulting optimal flip tax is 4%, which is close to the flat transfer tax rates imposed in global real estate markets. Consistent with empirical findings, the model predicts imposing higher sales taxes on second homes increases house price levels but entails large welfare gains for renters on the margin of homeownership.

Local governments recover missing revenues from overdue tax bills by auctioning off claims to homes in what is known as either a tax lien or tax deed sale. Using detailed data with information on over 18,000 tax lien sales and individuals' overdue tax payment histories from Washington, D.C. as a case study, I find prices of homes neighboring a tax lien sale property, on average, decline within the first two years of the sale, consistent with existing research on the local spillover effects of mortgage foreclosures. However, in already gentrifying areas, large positive pricing spillovers emerge within three years, driven by investors' conversion of former tax lien properties into luxury housing and commercial amenities. Underrepresented minority homeowners are more likely to be displaced by tax delinquency and less likely to transact homes in areas containing recent tax sales to institutional buyers. Private capital’s entry into the municipal finance ecosystem has amplified gentrification and the Black-white wealth gap.

Growing spatial inequality has led policymakers to enact tax breaks to attract corporate investment and jobs to economically peripheral regions. We demonstrate the importance of multi-plant firms' physical capital structure for the take-up and efficacy of place-based policies by studying a national bonus depreciation scheme in Japan which altered the relative cost of capital across locations, offering high-tech manufacturers immediate cost deductions from their corporate income tax bill. Combining corporate balance sheets with a registry containing investment by plant location and asset type, we find the policy generated big gains in employment and investment in building construction and in machines at pre-existing production sites, with an implied fiscal cost per job created of $16,000. For eligible firms, plant-level hiring in ineligible areas outstripped that in eligible areas, suggesting reallocation of resources within firms' internal capital and labor markets mitigates the spatial misallocation inherent in subsidizing low productivity areas.

How governments should choose the frequency of payments has received little attention in the literature on the optimal design of benefits programs. We propose a simple model in which the government chooses the interval length between payments, subject to a tradeoff between costs of providing more frequent benefits and welfare gains from mitigating consumption non-smoothing. Using a high-frequency retail dataset that links consumers to their purchase history, we apply the model to the Japanese National Pension System. Our evidence suggests suboptimal intra-cycle consumption patterns, with negligible retailer price discrimination. Model calibrations support the worldwide prevalence of monthly payment systems.

This paper documents heterogeneous spending out of a large stimulus tax rebate by exposure to the 1980s Japanese housing market turbulence. Linking geocoded household expenditure and financial transactions data to a new set of local housing price indices in Japan, we estimate a U-shaped pattern in the marginal propensity to consume with respect to housing price growth. Recipients living in areas with the smallest housing price gains during the 1980s spent 47% of the 1994 rebate within three months of payment, compared to 24% among recipients in areas which experienced the largest housing price gains. We find limited heterogeneity in marginal propensities to consume among households in less affected areas, but MPCs are higher for younger, renter households with no debt residing in more affected areas. Our results are consistent with near-rationality rather than a liquidity constraint story. Winners who are less exposed to housing risk respond more to payments, implying policies which target losers from housing market downturns may be less effective at stimulating consumption.
