Studies have focused heavily on money in the transmission mechanism of monetary policy. In this article we explore the empirical importance of credit. The paper provides a framework in which to analyse the balance sheets of, and financial flows between, different sectors of the UK economy, and an econometric model of the interactions between non-financial firms, households and credit offered by banks and non-bank financial intermediaries. The paper also provides a dynamic structural model of bank and building society credit, money and decisions to consume and invest and then adds credit from non-bank financial intermediaries. Our bottom line is that credit is an important part of the transmission process of UK monetary policy.

Empirical investigation of the external finance premium has been conducted on the margin between internal finance and bank borrowing or equities but little attention has been given to corporate bonds, especially for the emerging Asian market. In this paper, we hypothesize that balance sheet indicators of creditworthiness could affect the external finance premium for bonds as they do for premia in other markets. Using bond-specific and firm-specific data for China, Hong Kong, Indonesia, Korea, Philippines, Singapore and Thailand during 1995–2009 we find that firms with better financial health face lower external finance premia in all countries. When we introduce firm-level heterogeneity, we show that financial variables appear to be both statistically and quantitatively more important for financially constrained firms. Finally, when we examine the effects of the 1997–1998 Asian crisis and the 2007–2009 global financial crisis, we find that the sensitivity of the premium is greater for constrained firms during the Asian crisis compared to other times.

This paper examines firms’ access to bank and market finance when allowance is made for differences in firm-specific characteristics. A theoretical model determines the characteristics such as size, risk and debt that would determine firms’ access to bank or market finance; these characteristics can result in greater (or lesser) tightening of credit when interest rates increase. An empirical evaluation of the predictions of the model is conducted on a large panel of UK manufacturing firms. We confirm that small, young and risky firms are more significantly affected by tight monetary conditions than large, old and secure firms.

Trade credit is an important source of finance for firms and has been well researched, but the focus has been on financial trade-offs. In this paper, we consider the trade-offs with inventories and develop a simple model that recognizes the incentives a firm faces to offer and receive trade credit. Our model identifies the response of accounts payable and accounts receivable to changes in the cost of inventories, profitability, risk and liquidity, and importantly, this influence operates through a production channel. Our results support the model and complement many existing studies focused on explaining the financial terms of trade credit.

We analyze the impact of Covid-19 on productivity using data from an innovative monthly firm survey that asks for quantitative impacts of Covid-19 on inputs and outputs. We find that total factor productivity (TFP) fell by up to 6% during 2020–2021. The overall impact combined large reductions in ‘within-firm’ productivity, with offsetting positive ‘between-firm’ effects as less productive sectors, and less productive firms within them, contracted. Despite these large pandemic effects, firms’ post-Covid forecasts imply surprisingly little lasting impact on aggregate TFP. We also see significant heterogeneity over firms and sectors, with the greatest impacts in those requiring extensive in-person activity.
