“…Rather, the aim in carrying out leximetric coding is precisely to arrive at a measure of the normative content of legal rules which is separate from measures of their impact and effect, so that potential causal relationships between legal phenomena and these other variables of interest can be identified. Evidence of the effectiveness of a rule in practice is available through other sources, such as the evidence on court efficiency and enforcement levels analysed for the Indian case by Fagernäs (2010), or evidence on employer and worker perceptions of the operation of the law in practice of the kind which are collected via workplace surveys for some other countries (see, for example, van Wanrooy et al, 2007, on Australia). Evidence on the economic variables to which legal phenomena might be related, either as causal or outcome variables, are available through sources which include national, sectoral and company level data on economic and financial performance, of the kind we use in our econometric analysis, to which we now turn.…”
