However, a long-standing problem for innovation scholars is obtaining causal estimates from observational i. For a long time, causal inference from cuasal surveys has been what is causal evidence impossible.

Hal Varian, Chief Economist at Google and Emeritus Professor at the University of California, Berkeley, commented on the value of machine learning techniques for econometricians:. My standard advice to graduate students these days is go to the computer science department and take a class in machine learning. There have been very fruitful collaborations between computer scientists and statisticians in the last decade or so, and I expect collaborations between computer scientists and econometricians will also be productive in the future.

Hal Varianp. This paper seeks to transfer knowledge from computer science and machine learning communities into the economics of innovation and firm growth, by offering an accessible introduction to techniques for data-driven causal inference, as well as three applications to innovation survey datasets that are expected to have several implications for innovation policy. The contribution of this paper is to introduce a variety of techniques including very recent approaches is although a causal conjunction causal inference to the toolbox of econometricians and innovation scholars: a conditional independence-based approach; additive noise models; and non-algorithmic inference by hand.

These statistical tools are data-driven, rather than theory-driven, and can be useful alternatives to obtain causal estimates from observational data i. While several papers have caysal introduced the conditional independence-based approach Tool 1 in economic contexts such as monetary policy, macroeconomic SVAR Structural Vector Autoregression models, and corn price dynamics e. A further contribution is that these new techniques are applied to three contexts in the economics of innovation i.

While most analyses of innovation datasets focus on reporting the statistical associations found in observational data, policy makers need causal evidence in order to understand if their interventions in a complex system of inter-related variables will have the expected outcomes. This paper, therefore, seeks to elucidate the causal relations between innovation variables using recent methodological advances in machine learning. While two recent survey papers what do domino mean in spanish the Fausal of Economic Perspectives have highlighted how machine learning techniques can provide interesting results regarding statistical associations e.

Section 2 presents the three tools, and Section 3 describes our CIS dataset. Section 4 contains the three empirical contexts: funding for innovation, information sources for innovation, and innovation expenditures and firm growth. Section 5 concludes. In the second case, Reichenbach evdience that X and Y are conditionally independent, given Z, i. The fact that all three cases can also occur together is an additional obstacle for causal inference. For this study, we will mostly assume that only wvidence of the cases occurs and try to what is causal evidence between them, subject to this assumption.

We are aware of the fact that this oversimplifies many real-life situations. However, even if the cases interfere, one of the three types of causal links may be more significant than the others. It is also more valuable for practical purposes to focus on the main causal relations. A graphical approach is useful for depicting causal relations between variables Pearl, This condition implies that indirect distant causes become irrelevant when the direct proximate causes are known.

Source: the authors. Figura 1 Directed Acyclic Graph. The density of the joint distribution p x 1x 4x 6evidemce it exists, can therefore be rep-resented in equation form and factorized as follows:. The faithfulness assumption states what is causal evidence only those conditional independences occur that are implied by the graph structure. This implies, for instance, that two variables with a common cause will what is emergent readers be rendered statistically independent by structural parameters that - by what is effect affect, perhaps - are fine-tuned to si cancel each other out.

This is conceptually similar to the assumption that one object does not perfectly conceal a second object directly behind it that is eclipsed from the line of sight of a viewer located at a specific view-point Pearl,p. In terms of Figure 1faithfulness requires that the direct effect of x 3 on x 1 is not calibrated to be perfectly cancelled out by the indirect evisence of x 3 on x 1 operating via x 5. This perspective is motivated by a physical picture of causality, according to which variables may refer to measurements in space and time: wha X i and X j are variables measured what is causal evidence different locations, then every influence of X i on X j requires a physical signal propagating through space.

Insights into the causal relations between variables can be obtained wgat examining patterns of unconditional and conditional dependences between variables. Bryant, Bessler, and Haigh, and Kwon and Bessler show how the use of a third variable C can elucidate the causal relations between variables A what is causal evidence B by using three unconditional independences. Under several assumptions 2if there is statistical dependence between A and B, and statistical dependence between A and C, but B is statistically independent of C, then we can prove that A does not cause B.

In principle, dependences could be only of higher order, i. HSIC thus measures dependence of random variables, such as a correlation coefficient, with the difference being that it accounts also for non-linear dependences. For multi-variate Gaussian distributions 3conditional independence can be inferred from the covariance matrix by computing partial correlations. Instead of using the covariance matrix, we describe the following more intuitive way to obtain partial correlations: let P X, Y, Z be Gaussian, then X independent of Y given Z is equivalent to:.

Explicitly, they are given by:. Note, evidencd, that in non-Gaussian distributions, vanishing of the partial correlation on the left-hand side of 2 is neither necessary nor sufficient for X independent of Y given Z. On the one hand, there could be higher order dependences not detected by the correlations. On the other hand, the influence of Z on X and Y could be non-linear, and, in this case, it would not caussl be screened off by a linear regression on Z.

This is why using partial correlations instead of independence tests can introduce two types of errors: namely accepting independence even though it does not hold or rejecting it even though it holds even in the limit of infinite sample what is causal evidence. Conditional independence testing is a challenging problem, and, therefore, we always trust the results of unconditional tests more than those of conditional tests. If their independence is accepted, then X independent of Y what is causal evidence Z necessarily holds.

Hence, we have in the infinite sample limit only the risk of rejecting independence although it does hold, while the second type of error, namely accepting conditional independence although it does not hold, is only possible due to finite sampling, but not in the infinite sample limit. Consider the case of two variables A and B, which are unconditionally independent, and then become dependent once conditioning on a third variable C. The only logical interpretation of such a statistical pattern in terms of causality given that there are no hidden common causes would be that C is caused by A and B i.

Another illustration of how causal inference can be based on conditional and unconditional independence testing is pro-vided by the example of a Y-structure in Box 1. Instead, ambiguities may remain and some causal relations will be unresolved. We therefore complement the conditional independence-based approach with other techniques: additive noise models, and non-algorithmic inference by hand.

For an what is causal evidence of these more recent techniques, see Peters, Janzing, and Schölkopfand also Mooij, Peters, Janzing, Zscheischler, and Schölkopf for extensive performance studies. Let us consider the following toy example of a pattern of conditional independences that admits inferring a definite causal influence from X on Y, despite possible unobserved caisal causes i. Z 1 is independent of Z evixence. Another example including hidden common causes the grey nodes is shown on the right-hand side.

Both causal structures, however, coincide regarding the causal relation between X and Y whag state that X is causing Y in what is causal evidence unconfounded way. In other words, the statistical causzl between X and What is difference between sociology and anthropology is entirely due to the influence qhat X on Y without a hidden common cause, see Mani, Cooper, and Spirtes and Section 2.

Similar statements hold when the Y structure occurs as a subgraph of a larger DAG, evidnece Z 1 and Z 2 become independent after conditioning on some additional set of variables. Scanning quadruples of variables in the search for independence patterns from Y-structures can aid causal inference. The figure on the left shows the simplest possible Evidencs. On the right, there is a causal structure involving latent variables these unobserved variables are marked in greywhich entails the same conditional independences on the observed variables as the structure on the left.

Since conditional independence testing is a difficult statistical problem, in particular when one conditions on a large number of variables, we focus on a subset of variables. We first test all unconditional statistical independences between X and Y for all pairs X, Y of variables in this set. To avoid serious what is the basic relationship between language and literature issues and to increase the reliability of every single test, we do not perform tests for independences of the form X independent of Y conditional on Z 1 ,Z 2We then construct an what is causal evidence graph where we connect each pair that is neither unconditionally nor conditionally independent.

Whenever the number what is causal evidence of variables is larger than 3, it is possible that we obtain too many edges, because independence tests conditioning on more variables could render X and Y independent. We evidnce this risk, however, for the above reasons. In some cases, the pattern of conditional independences also allows the direction of some of the edges to be inferred: whenever the resulting undirected graph contains the what is causal evidence X - Z - Y, where X and Y are non-adjacent, and we observe that X and What is causal evidence are independent but conditioning on Z renders them dependent, then Z must be the common effect of X and Y i.

For this reason, we perform conditional independence tests also for pairs of variables that have already been verified to be unconditionally independent. From the point of view of constructing the skeleton, i. This argument, like the whole procedure above, assumes causal sufficiency, i. It is therefore remarkable that the additive noise method below is in principle under certain admittedly strong assumptions able to detect the presence of hidden common causes, see Janzing et al.

Our second technique builds on insights that causal inference can exploit statistical information contained in the distribution of the error terms, and it evvidence on two variables at a time. Causal inference based on additive noise models ANM complements the conditional independence-based approach outlined in the previous section because it can distinguish between possible causal directions between variables that have the same set of conditional independences.

With additive noise models, inference proceeds by analysis of the patterns of noise between the variables or, put differently, the distributions of the residuals. Assume Y is a function of X up to an independent and identically distributed IID additive noise term that is statistically independent of X, i. Figure 2 visualizes the idea showing that the noise can-not be independent in both directions. To see a real-world example, Figure 3 shows the first example from a database containing cause-effect variable pairs for which we believe to know the causal direction 5.

Up what does it mean spiritually to get stung by a bee some noise, Y is given by a function of X which is close to linear apart from at low altitudes. Phrased in terms of the language above, writing X as a function of Y yields a residual error term that is highly dependent on Y.

On the other hand, writing Y as a function of X hwat the noise term that is largely homogeneous along the x-axis. Hence, the noise is almost independent of X. Accordingly, additive noise based causal inference really infers altitude to be the cause of temperature Mooij et al. Furthermore, this example of altitude causing temperature rather than vice versa highlights how, in a thought experiment of a cross-section of paired altitude-temperature datapoints, the causality runs from altitude to temperature even if our cross-section has no information on time lags.

Indeed, are not always necessary for causal inference 6and causal identification can uncover instantaneous effects. Then do the same exchanging the roles of X and Y.
