The Behavior Change Technique Taxonomy (v1) of 93 Hierarchically Clustered Techniques: Building an International Consensus for the Reporting of Behavior Change Interventions

Abstract: CONSORT guidelines call for precise reporting of behavior change interventions: we need rigorous methods of characterizing active content of interventions with precision and specificity. The objective of this study is to develop an extensive, consensually agreed hierarchically structured taxonomy of techniques [behavior change techniques (BCTs)] used in behavior change interventions. In a Delphi-type exercise, 14 experts rated labels and definitions of 124 BCTs from six published classification systems. Another 18 experts grouped BCTs according to similarity of active ingredients in an open-sort task. Inter-rater agreement amongst six researchers coding 85 intervention descriptions by BCTs was assessed. This resulted in 93 BCTs clustered into 16 groups. Of the 26 BCTs occurring at least five times, 23 had adjusted kappas of 0.60 or above. “BCT taxonomy v1,” an extensive taxonomy of 93 consensually agreed, distinct BCTs, offers a step change as a method for specifying interventions, but we anticipate further development and evaluation based on international, interdisciplinary consensus.

Financial Intermediation and Growth: Causality and Causes

Abstract: Legal and accounting reform that strengthens creditor rights, contract enforcement, and accounting practices boosts financial development and accelerates economic growth. Levine, Loayza, and Beck evaluate: Whether the level of development of financial intermediaries exerts a casual influence on economic growth. Whether cross-country differences in legal and accounting systems (such as creditor rights, contract enforcement, and accounting standards) explain differences in the level of financial development. Using both traditional cross-section, instrumental-variable procedures and recent dynamic panel techniques, they find that development of financial intermediaries exerts a large causal impact on growth. The data also show that cross-country differences in legal and accounting systems help determine differences in financial development. Together, these findings suggest that legal and accounting reform that strengthens creditor rights, contract enforcement, and accounting practices boosts financial development and accelerates economic growth. This paper - a product of Macroeconomics and Growth, Development Research Group - is part of a larger effort in the group to understand the links between the financial system and economic growth.

Finance and the Sources of Growth

Abstract: Development of the banking sector exerts a large, causal impact on total factor productivity growth, which in turn causes GDP to grow. Whether banking development has a long-run effect on capital growth or private saving remains to be seen. Beck, Levine, and Loayza evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources- total factor productivity growth, physical capital accumulation, and private saving. They use (1) a pure cross-country instrumental variable estimator to extract the exogenous component of banking development and (2) a new panel technique that controls for country-specific effects and endogeneity. They find that: - Banks do exert a large, causal impact on total factor productivity growth, which feeds through to overall GDP growth. - The long-run links between banking development and both capital growth and private savings are more tenuous. This paper - a product of Finance, Development Research Group - is part of a larger effort in the group to understand the links between the financial system and economic growth.

A New Database on Financial Development and Structure

Abstract: This new database of indicators of financial development and structure across countries and over time unites a range of indicators that measure the size, activity, and efficiency of financial intermediaries and markets. Beck, Demirguc-Kunt, and Levine introduce a new database of indicators of financial development and structure across countries and over time. This database is unique in that it unites a variety of indicators that measure the size, activity, and efficiency of financial intermediaries and markets. It improves on previous efforts by presenting data on the public share of commercial banks, by introducing indicators of the size and activity of nonbank financial institutions, and by presenting measures of the size of bond and primary equity markets. The compiled data permit the construction of financial structure indicators to measure whether, for example, a country's banks are larger, more active, and more efficient than its stock markets. These indicators can then be used to investigate the empirical link between the legal, regulatory, and policy environment and indicators of financial structure. They can also be used to analyze the implications of financial structure for economic growth. Beck, Demirguc-Kunt, and Levine describe the sources and construction of, and the intuition behind, different indicators and present descriptive statistics. This paper - a product of Finance, Development Research Group - is part of a broader effort in the group to understand the determinants of financial structure and its importance to economic development.
