A municipal analyst in Brazil asks a question; you answer it by choosing registered tools and their arguments. The tools compute every number. Your job is to recognise how the data were generated, pick the tool whose design matches, read what it reports, and say what the result means for the analyst.\n\n# Rules\n1. You never compute a number. Every number in your answer must have been stated by a tool call in this run (a figure, its standard error or interval, a diagnostic, a table cell) or written in the question. No mental arithmetic: for a ratio, difference, sum, product, percent change or share of figures already computed, call calc.combine; to restate a log-point coefficient as a percent or an effect in standard deviations, call core.scale_effect.\n2. Before estimating, work out the design: how units came to be treated (a lottery, an offer with partial take-up, a threshold of a running variable, a policy that started on one date or on different dates, self-selection), what a row is, and which columns hold the outcome, treatment, unit, time, running variable, instrument, cluster and survey weight. Call data.describe when the columns are unclear. Then choose the tool whose \"Use when\" matches and heed its \"Avoid when\".\n3. Read the diagnostics, warnings and \"Check after\" items a result returns before you trust a figure. If a diagnostic says the design fails — a weak instrument, sorting at the cutoff, few clusters, non-parallel pre-trends — say so plainly and do not present the estimate as causal.\n4. If no tool fits the design, or the data cannot identify what is asked, decline and say what is missing. Never invent a design, a column or a number.\n5. A tool that errors or declines returns its reason; fix the arguments and call again, or choose another tool.\n6. Before each tool call, write one sentence on why this tool and these arguments fit the design. It is recorded as your rationale.\n7. Finish with submit_answer. Write the answer in the language of the question (Portuguese: decimal comma), short and direct: the estimate with its uncertainty, the design that identifies it, and what could undermine it. List in figure_refs every figure you quote, as '<call_id>:<key>' (each tool result carries its call_id), and put diagnostics that limit the conclusion in caveats. Write numbers as the tools stated them; do not quote rule-of-thumb thresholds as numbers.\n\n# Skills\nProcedures for kinds of problems. Load one with load_skill(name) when the right design is not obvious:\n- choose-identification-strategy: Decide which design identifies the effect a question asks about - an experiment, an instrument, a discontinuity, differences-in-differences, fixed effects or none - from how treatment was assigned and what the data record. Load it whenever a question asks for an effect and the right estimator is not obvious.\n- differences-in-differences: Estimate the effect of a policy adopted by some units and not others by comparing changes over time - the classic two-group two-period design, and staggered adoption across periods, where two-way fixed effects fails when effects vary. Load it for laws passed in one municipality, programs rolled out over several years, and any before-and-after comparison with a control group.\n- evidence-pooling: Combine published estimates of the same effect from several studies into one random-effects average, checking that they are independent, in the same unit and about the same outcome, and reporting how much they disagree. Load it when a question lists studies with estimates and standard errors or intervals and asks what the literature finds.\n- experiments-and-power: Estimate the effect of a randomized program (by individual or by cluster, large or tiny samples) and plan an evaluation - how many units are needed, or what effect a fixed sample can detect. Load it for lotteries, pilots, randomized rollouts and any sample-size or power question.\n- instrumental-variables: Estimate the effect of a self-selected or endogenous regressor with an instrument - a randomized offer with partial take-up, distance, eligibility rules, a lottery - and judge whether the instrument is strong and plausibly excluded. Load it when the question warns that those who take a treatment differ from those who do not.\n- panel-fixed-effects: Relate an outcome to a regressor that varies over time within the same units - municipalities, schools, firms observed for several years - removing fixed unobserved differences between units, and recognise when a pooled comparison across units misleads (Simpson's paradox). Load it for panels and \"within the same municipality over time\" questions.\n- poverty-and-inequality: Measure poverty (headcount, gap, severity at a given line) and inequality (Gini, Palma, Theil) from household survey microdata - with the survey weights, the income concept and the period the line is defined in. Load it for any question about how many are poor or how unequal incomes are.\n- regression-discontinuity: Estimate an effect where treatment switches at a threshold of a running variable - vote margins, eligibility scores, population thresholds for transfers, age cutoffs - and test for manipulation around the threshold before trusting it. Load it for close elections, eligibility cutoffs and any \"just above versus just below\" question.\n- reporting-numbers: Write the final answer so that every number is traceable - quote only what tools stated, cite each figure by reference, do derived arithmetic with a tool, and state uncertainty and caveats. Load it before submitting an answer that needs a ratio, a difference, a percent or a conversion.\n\n# Datasets\nPass a dataset's id as the `dataset` argument.\n{\n \"id\": \"wage\",\n \"rows\": 935,\n \"description\": \"To estimate the impact of an additional year of education on hourly wage, we look at a sample size representing individuals with varying levels of education and their hourly wages.

Wait, *is* hourly wage directly provided, or do we need to calculate it? Is `wage` total yearly income or monthly? And is `hours` weekly or monthly? I'm going to assume that it needs to be calculated, since the prompt states we must calculate based on the given variables.

Okay, I see: `dataset`, `y`, `x`, `controls`, `weights`, `se`, `cluster`, `subset`, `intercept`, `level`, and `fe`.\n\nHold on a second... `infer.ols` is expecting the dependent variable, `y`, as a *column name* within the dataset.

Let me check the documentation... the description explicitly states `y`: \"Outcome column.\" Okay, that clarifies things.\n\nNow, a critical point... does the `wage` dataset actually have a column representing hourly wage? Or do I need to calculate it from existing columns? Or is there only a direct column name for the hourly wage? Before I get too far down this path, let's take a quick look at the dataset's structure using `data.describe` to see what columns are available and if there's any obvious choice for that `y` variable.

The prompt is asking for the percentage increase in hourly wage per year of education, using linear regression. Importantly, I need to stick to just wage, hours, and education. No extraneous variables.\n\nWait, the dataset! This *has* to be Wooldridge's `wage2` dataset – it just fits the description too perfectly. The sample size of 935 observations, wage mean, hours mean, IQ mean, educ mean... that rings a bell. Yup, it's definitely the Wooldridge dataset. Specifically, it's the `WAGE2.RAW` dataset. In this dataset, I recall that `wage` is monthly earnings in 1980 dollars (or is it weekly?). And I need to recall the details of this specific Wooldridge dataset: `wage` is monthly earnings, `hours` is weekly hours, `IQ` is IQ score, `educ` is years of education, and `exper` is tenure.\n\nNow, the question is how to get the hourly wage and what format the regression model will accept. The key is to calculate hourly wage by dividing `wage` by `hours`. Does `infer.ols` accept this kind of expression, like `log(wage/hours)`? Or, will it only handle column names directly? I need to test that. I'll test passing `y=\"wage\"` first. I will check to see if an expression works. I need to make sure I can correctly input this into the code and obtain the correct estimate.\n\n\n","vendor":true,"wall_ms":6301.578082842752}}

I'll utilize a try-except block, or just run a simple test with transformations, to observe the function's behavior.

It's telling me the 'log(wage/hours)' column isn't there, which is a key indicator of where things are heading. The available columns are only these standard ones, and the error threw me off because it's not clear what is needed.\n\nAlright, time to re-read the prompt. It's asking for the percentage increase in *hourly* wage for each year of education, using linear regression, and to *only* consider 'wage', 'hours', and 'educ'. It's very specific about excluding other variables.\n\nNow the question is coming into focus. Does \"do not consider variables other than 'wage', 'hours', and 'educ'\" mean to regress `wage` on `educ` *and* `hours`? That interpretation seems to be correct, as I have to find the effect of education on wage.\n\nOkay, let's unpack that. If I regress `wage` on both `educ` and `hours`, what's the interpretation? It could mean `wage` is actually a total income (like monthly earnings = hourly wage * hours), the model needs to be formed. The question also specifies percentage increase. What if I regress `wage` on `educ` and `hours`?\n\nBut wait – why does the question specifically ask for a *percentage* increase? Linear regression spits out coefficients, not directly percentages. I need to figure out how to translate a coefficient into a percentage increase in hourly wage. It's a key question.\n\nTime to check what I have available. I need to recall the appropriate skills: I could use `load_skill('choose-identification-strategy')` to figure out which approach is correct, or possibly I need `load_skill('reporting-numbers')` to get that percentage increase.\n\n\n","vendor":true,"wall_ms":7404.706458095461}}

I need to understand how education impacts hourly wage, and the key is this `core.scale_effect` function. It seems to translate model coefficients into interpretable effects: percent, standard deviations, etc. The description outlines the transformations: `log_points_to_percent`, `sd_units`, and `percent_of_baseline`.\n\nSpecifically, `percent_of_baseline` is grabbing my attention. It's defined as `100 * b / baseline`. This rings a bell.  In a standard linear model ($Y = \\beta_0 + \\beta_1 X + ...$), the percentage increase in $Y$ for a one-unit change in $X$ is indeed $\\frac{\\beta_1}{\\bar{Y}} \\times 100\\%$.  That *is* essentially `percent_of_baseline`!\n\nNow, the crucial question: what does $Y$ represent here? Is it \"hourly wage\" or just \"wage\"? I'm going back to the prompt and data description to be absolutely certain.\n\nAh, here's the dataset description. It specifies: \"The columns in this dataset include 'wage', representing the *total income*; 'hours', representing the *total hours worked*; and 'educ', representing the *years of education*\". Crucially, it uses the term \"total income\" and \"total hours\".\n\nSo, can I regress `wage` on `educ` and `hours`? My thinking now is that I *can* regress `wage` on `educ` and `hours`, since \"wage\" is the total income. Specifically, the data description is using the term \"total income\" when referring to \"wage\".\n\nTo actually test this, I'll use `infer.ols`. The dependent variable, `y`, will be \"wage\". The main independent variable, `x`, will be \"educ\". I'll consider two options: including \"hours\" as a control variable (i.e. `controls: [\"hours\"]`) *or* including \"hours\" as an independent variable (i.e. `x: [\"educ\", \"hours\"]`).

The user wants a percentage increase in hourly wage per year of education, derived using linear regression, and crucially, they're explicitly limiting the analysis to \"wage,\" \"hours,\" and \"educ.\" That restriction on variables is the key. My immediate thought was, can I construct hourly wage directly? Unfortunately, there's no way to create a new column via data transformation. \n\nI checked all available tools to make sure. I also reread the prompt. The dataset is described as containing data on individuals' hourly wages. However, the variables in `wage.csv` include 'wage', 'hours', and 'educ'. At first, I was confused. Does \"wage\" in the dataset already represent the hourly wage?\n\nThen I reread the prompt again. It says that \"wage\" represents *total* income. The prompt is designed to emphasize the inclusion of \"hours\". The key here is the user specifically wrote \"do not consider variables other than 'wage', 'hours', and 'educ'.\" This is important because the dataset also contains other variables. If the user only wanted to regress \"wage\" on \"educ\", the prompt would say \"do not consider variables other than 'wage' and 'educ'\".\n\nSo, it's a regression of \"wage\" (total income) on \"educ\" (years of education) *and* \"hours\" (total hours worked). This is not a simple OLS. My focus shifts to the implication of controlling for hours. What does the inclusion of 'hours' in the regression equation mean?\n\nI remember the regression equation would look something like: Wage = β₀ + β₁Educ + β₂Hours + ε. The user's question asks what the effect on hourly wage is. But what if we hold the hours constant? If $Wage = HourlyWage \\times Hours$, then holding $Hours$ fixed, the change in income with respect to education is $\\beta_1 = \\frac{\\partial Wage}{\\partial Educ}$.\n\nIf hours is fixed, the percentage change in hourly wage would be the same as the percentage change in total wage: holding hours constant, so the model must be:\n\n$\\ln(HourlyWage) = \\ln(Wage) - \\ln(Hours)$.\n\nHolding hours constant, $\\% \\Delta HourlyWage = \\% \\Delta Wage$!\n\nThe effect of education, holding hours constant, is then $\\beta_1$. The percentage increase in hourly wage (or wage), per year of education, is calculated as the coefficient on education divided by the mean wage. The mean cancels out the hourly variable. That is:\n\n$\\frac{\\beta_{educ}}{\\bar{Wage}} \\times 100\\%$!\n\nThe regression should return the relevant information. I recall that the regression that used \"educ\" and \"hours\" gave the same answer as the regression of \"wage\" on \"educ\" with \"hours\" as a control. The explicit instruction to include \"hours\" in the regression is critical.

I need to refresh my memory on what parameters it expects. Right, the key ones are `baseline`, `coefficient`, `sd`, and `transform`. The `transform` parameter looks particularly important, allowing us to specify how the effect is scaled. It can be 'log_points_to_percent', 'sd_units', or 'percent_of_baseline'.\n\nNow, let's put it to the test. I think I'll start with `transform='percent_of_baseline'`.  For the `coefficient`, I'll use the figure reference 'call_f86a6591:coef.educ', I know that should be available. And for the `baseline` value, let's grab 957.945. I remember that's what we got from the `data.describe` output. Perfect, I think this should give us a good starting point for evaluating how the function behaves in this specific context.

That's essentially 6.36%, rounded to the nearest hundredth of a percent. I immediately consider the implication: is that a meaningful result in the context of the model? Now, my mind immediately jumps to a potential scaling issue. What if we stripped out the hours dimension and checked the `core.scale_effect` on the educational coefficient? A quick peek at `call_6afedbe4:coef.educ` should do the trick. Just need to verify that.

And it needs to be to the nearest hundredth of a percent, so I'll keep that in mind.\n\nNow, let's get into the heart of it.  I need to provide an estimate for the percentage increase in hourly wage per year of education. The data involves 'wage', 'hours', and 'educ', and I'm using linear regression, which has been performed.\n\nLet me break down the calculations. It seems like I have two scenarios to consider: with and without controlling for hours worked.\n\nWhen I *do* control for `hours`:\n\n*   The coefficient on `educ` is 60.8777 (with a standard error of 6.16757 and a 95% confidence interval [48.7738, 72.9817]).\n*   This translates to a percentage of 6.35503% relative to the mean wage (957.945), which I'll round to 6.36% (with a 95% confidence interval [5.0915%, 7.61857%]).\n\nWithout controlling for `hours`:\n\n*   The coefficient on `educ` is 60.2143 (se: 6.15696, 95% CI [48.1312, 72.2974]).\n*   This translates to a percentage of 6.28578%, which is 6.29% (95% CI [5.02442%, 7.54713%]).\n\nNow, there's a little nagging thought – hourly wage is W/H. I need to make sure I'm using the mean of the ratio of wage to hours, or the ratio of means.  It turns out that I can't directly compute the mean of $W/H$ from the provided summary stats, but it's important to keep that in mind.\n\nOkay, let's see, has `percent_of_baseline` done the right scaling? I see the baseline mean of wage is 957.945, and with the regression I have:  `coef.educ` is 60.8777. So, the `effect` comes out as 6.35503%, which rounds to 6.36%.\n\nNow, before I present the answer, I need to check the caveats:\n\n*   This is observational data, and OLS estimates are vulnerable to omitted variable bias (things like ability, family background, school quality, or measurement error).  So, this is a conditional association, not necessarily a causal effect.\n*   The linear specification models an additive dollar increase per year of education.  The percentage return is at the sample mean.\n\nLet me make sure all my figure references and numbers are consistent:\n\n*   `call_f86a6591:coef.educ`: 60.8777\n*   `call_f86a6591:coef.hours`: -2.21664\n*   `call_af8e73fd:effect`: 6.35503\n*   `call_6afedbe4:coef.educ`: 60.2143\n*   `call_78bcdb6e:effect`: 6.28578\n\nAll seems correct and backed by the tools! I'm confident.\n\n\n","vendor":true,"wall_ms":14707.20645901747}}
