Non-technical summaryThe systemic financial crisis which engulfed the global economy from 2008, along with the subsequent sovereign debt crisis in the euro area, has led to the need to reassess the relationship between financial conditions and real economic activity. Within the context of the Macroprudential Research Network (MaRs), organized by the ESCB, one of the three workstreams is devoted to examining this relationship and the channels through which it operates.A prior question which arises is how exactly financial conditions should be depicted within models. Traditionally, macroeconometric models include only an interest rate. However, during periods of financial stress, changes in interest rates alone may not suffice to capture all the interactions between the financial system and the real economy. Variables such as credit aggregates, survey data reflecting the supply of loans and their terms and conditions, volatility in financial markets and spreads between various assets in different risk classes can all convey additional information on financial conditions and, in turn, influence economic activity through their effect on consumption, savings, investment and exports.In this paper, we seek to construct indices of financial conditions for the euro area and for selected individual euro area countries, which can be used to explore further macro-financial linkages in the economy at large. We construct indices which both exclude and include

This paper examines the cash flow sensitivity of investment using a panel of UK manufacturing firms to investigate the existence of a balance sheet channel. In addition to examining the impact of cash flow in different subsamples based on company size or financial policy, we investigate the extent to which investment becomes more sensitive to cash flow in periods of monetary tightness by employing a narrative indicator constructed for the United Kingdom. The results indicate that cash flow sensitivity in financially constrained firms is higher during periods of tight monetary policy and that financial constraints weaken with financial market sophistication.

The network is composed of economists from the European System of Central Banks (ESCB), i.e. the national central banks of the 27 European Union (EU) Member States and the European Central Bank. The objective of MaRs is to develop core conceptual frameworks, models and/or tools supporting macro-prudential supervision in the EU.The research is carried out in three work streams: 1) Macro-financial models linking financial stability and the performance of the economy; 2) Early warning systems and systemic risk indicators; 3) Assessing contagion risks.MaRs is chaired by Philipp Hartmann (ECB). Paolo Angelini (Banca d'Italia), Laurent Clerc (Banque de France), Carsten Detken (ECB), Simone Manganelli (ECB) and Katerina Šmídková (Czech National Bank) are workstream coordinators. Javier Suarez (Center for Monetary and Financial Studies) and Hans Degryse (Katholieke Universiteit Leuven and Tilburg University) act as external consultants. Fiorella De Fiore (ECB) and Kalin Nikolov (ECB) share responsibility for the MaRs Secretariat.The refereeing process of this paper has been coordinated by a team composed of Gerhard Rünstler, Kalin Nikolov and Bernd Schwaab (all ECB).The paper is released in order to make the research of MaRs generally available, in preliminary form, to encourage comments and suggestions prior to final publication.

This article looks at the empirical consequences of introducing endogenous capital depreciation in the standard neoclassical model with quadratic adjustment costs. To this end, we formulate an empirical specification that accommodates capital maintenance and utilization in the Euler equations for aggregate investment. The empirical estimates with data from the Canadian Survey on Capital and Repair Expenditures show that, in contrast to the existing literature, the performance of the Euler equations is improved when we account for the impact of variable capital depreciation.
