During the mid and late 1990s young, high-tech firms in the US experienced a supply shift in both internal and external equity fueling a finance-driven boom in corporate R&D. This paper examines whether R&D spending in Europe in a similar way was sensitive to fluctuations in the supply of internal and external equity during the late 1990s and early 2000s. I conjecture that UK and Continental Europe, due to their different financial systems, differ in terms of equity supply. I estimate dynamic R&D regression models for UK and Continental European high-tech firms separately and find significant joint cash-flow effects for newly listed firms in both samples. However, only new firms in the UK experienced a joint external equity effect as well. The findings of this paper suggest a channel through which market-based financial systems outperform the bank-based economies of Continental Europe.

The high-tech sector accounts for the majority of corporate innovation in modern economies. In a sample of 38 countries, we document a strong positive relation between the initial size of the country's high-tech sector and subsequent rates of GDP and total factor productivity growth. We also find a strong positive connection between a country's equity (but not credit) market development and the size of its high-tech sector. Our main difference-in-differences estimates show that better developed stock markets support faster growth of innovative-intensive, high-tech industries. The main channels for this effect are higher rates of productivity and faster growth in the number of new high-tech firms. Credit market development fosters growth in industries that rely on external finance for physical capital accumulation but is unimportant for growth in innovation-intensive industries. These findings show that stock markets and credit markets play important but distinct roles in supporting economic growth. Stock markets are uniquely suited for financing technology-led growth, a particularly important concern for advanced economies.

The economic disruption from the COVID-19 pandemic prompted governments around the world to initiate an unprecedented number of temporary lending and tax deferment programs. Which firms will benefit from these programs? What are the implications for firm balance sheets and post-crisis survival? We provide some novel insights on these questions by studying one of the first government programs of this type, which Sweden launched at the height of the 2008–2009 financial crisis. The Swedish program allowed firms to temporarily suspend payment of all labor-related taxes and fees, treating these deferred amounts as a short-term loan from the government. Firms participating in the program are younger, less profitable, hold fewer cash reserves, are more leveraged, and have less unused slack in their credit lines when the crisis hits. Given the structure of the Swedish program, it provided more liquidity to firms with relatively larger ex ante wage bills. Exploiting this feature of the policy, we find that firms use the program to increase overall debt levels rather than to substitute for other borrowing. The leverage increase is due entirely to higher levels of non-bank debt. Firms use the funds to avoid making even deeper cuts to current assets. Despite the increase in leverage, access to the lending program is unrelated to the likelihood a firm files for bankruptcy and is negatively related to the likelihood a firm encounters severe financial distress in the years immediately following the crisis.

Higher country taxes on noxious manufacturing emissions lead to substantial increases in firms’ R&D spending. The R&D response is entirely driven by those high-pollution firms most affected by emissions taxes. Pollution taxes increase the marginal value of R&D spending in polluting firms, even when this spending does not lead to new innovation. Pollution taxes have the strongest effect on R&D investment in sectors in which new invention is difficult to appropriate and outside knowledge is easier to acquire, suggesting an important reason dirty firms invest in R&D is to expand their capacity to absorb external knowledge and technical know-how.

An important literature emphasizes that finance grew rapidly after WWII relative to the full economy and the services sector, but these are poor benchmarks because they mask a broad structural shift from low- to high-skill services. We show that i) finance is among the most skill-intensive service industries, ii) the evolution of the finance income share closely tracks other high-skill service industries, and iii) finance grew much slower than the rest of high-skill services in the post-WWII period. The rise of modern finance is not as remarkable as prior research suggests, providing context for debates about the size of finance.

We study a broad sample of firms across 32 countries and find that strong shareholder protections and better access to stock market financing lead to substantially higher long‐run rates of R&D investment, particularly in small firms, but are unimportant for fixed capital investment. Credit market development has a modest impact on fixed investment but no impact on R&D. These findings connect law and stock markets with innovative activities key to economic growth, and show that legal rules and financial developments affecting the availability of external equity financing are particularly important for risky, intangible investments not easily financed with debt.

Sweden was one of the first countries to introduce a carbon tax back in 1991. We assemble a unique data set tracking CO2 emissions from Swedish manufacturing firms over 26 years to estimate the impact of carbon pricing on firm-level emission intensities. We estimate an emission-to-pricing elasticity of around two, with substantial heterogeneity across subsectors and firms, where higher abatement costs and tighter financial constraints are associated with lower elasticities. A simple calibration suggests that 2015 CO2 emissions from Swedish manufacturing would have been roughly 30% higher without carbon pricing.
