Start by framing your research question clearly at the top of your introduction and explain why the 2019–2023 UK national minimum wage increases matter for youth (16–24) unemployment in London. Briefly set out the economic theory linking minimum wages to unemployment (basic labour demand and supply, monopsony and wage floor effects) and define key terms (youth unemployment rate, National Minimum Wage/National Living Wage, London labour market). Use one or two simple diagrams (labour market supply and demand, or a short-run labour demand curve) to show expected effects, and state your aim: to measure the impact of those wage increases on youth unemployment in London between 2019 and 2023. Mention the five-year rule to justify the time frame and note obvious contextual shocks that must be controlled for (COVID-19 pandemic, Brexit-related changes, sectoral shifts in hospitality/retail and changes in hours/furlough schemes) so the reader understands constraints from the start. Plan your methodology before you collect data. Prioritise reliable secondary sources: ONS and Nomis for regional/age-specific unemployment and participation rates, LFS microdata for age 16–24, DWP statistics, Bank of England and academic papers for macro controls, and statutory NMW/NLW rates from gov.uk. Consider primary data only if you can ethically and feasibly collect employer or youth survey information, but secondary time-series and regional microdata will be sufficient. Use descriptive statistics and visualisations (time-series plots, age cohort comparisons, sectoral employment shares) to identify trends, then apply an econometric approach to isolate the wage effect: difference-in-differences using a comparison group (e.g., older cohorts 25–34 or other UK regions less affected by London-specific shocks), or an interrupted time-series / panel regression with controls for GDP growth, sectoral employment, COVID restrictions, and seasonality. Explain variable construction, show sample calculations, and perform robustness checks (alternative age bands, lagged effects, placebo tests). Document all sources and justify chosen methods in the methodology section. In the analysis and writing, balance quantitative results with economic interpretation. Present tables and labelled charts in the main body and appendices, report coefficient sizes with confidence intervals and translate them into intuitive effects (e.g., percentage-point changes in unemployment among 16–24-year-olds). Link each empirical finding back to theory and real-world factors—explain why an observed change could be due to minimum wage increases, pandemic recovery, or sectoral composition. Make mini-conclusions at the end of each subsection to build toward your final answer. In the conclusion restate your aim, give a measured answer to the research question, discuss limitations (data quality, omitted variable bias, short post-treatment window), and suggest how future work could extend the study. Keep meticulous referencing (choose one citation style) and include raw data, regression output, and survey instruments in appendices.

Start by framing your research question clearly at the top of your introduction and explain why it matters for Mexico City's public health and economic policy. Summarize the policy (2020 excise tax on sugar-sweetened beverages) and define key terms such as per capita consumption, retail sales, and carbonated soft drinks, linking them to relevant economic concepts (demand, price elasticity, externalities, tax incidence). Keep the five-year rule in mind and justify the chosen 2020–2022 window. State your aim: to measure the magnitude and significance of changes in consumption and sales attributable to the tax, not to judge the policy normatively. Use a short literature review to position your study—cite empirical studies of soda taxes, ideally from Mexico and comparable cities, to show common methods and expected effect sizes, and use this to motivate your hypotheses and the variables you will analyse.

Design a clear methodology that mixes reliable secondary data with possible primary evidence if feasible. For secondary data, seek official government datasets (Mexico City health and tax revenue agencies), national statistical institutes, Euromonitor/Statista for retail sales, and market scanner data if available; ensure you document access restrictions and any aggregation differences. If you include primary data, limit it to a short retailer survey or observational price checks and explain sampling limits. Pre-process data to produce per capita measures (use population estimates) and adjust monetary figures for inflation and seasonality. Use descriptive statistics, time-series graphs, and simple econometric tests: interrupted time series, difference-in-differences with a comparable control (another Mexican city without the tax if possible), or regression with controls for income, unemployment, COVID-related mobility restrictions, and substitution to non-carbonated beverages. Report all formulas, test statistics, confidence intervals, and robustness checks (alternative windows, excluding 2020 pandemic months).

Structure the analysis so each section builds to the answer to your research question. Present data tables and annotated charts that highlight trends, followed by clear interpretation linking results to economic theory (e.g., estimated elasticity, incidence on consumers vs producers). Make mini-conclusions after each analytical subsection and discuss threats to validity—confounding pandemic effects, cross-border shopping, informal sales, data quality. In the final conclusion restate the aim, summarize quantitative findings and their significance, answer the research question explicitly (to what extent the tax reduced consumption and sales), and evaluate limitations and suggestions for extending the study. Include a complete bibliography and appendices with raw data, code and survey instruments.

Start by framing the research question clearly in your introduction and explain why the ECB’s quantitative easing from 2015–2020 is plausibly linked to Madrid residential prices. State the aim (to measure impact on prices) and situate the question in economic theory: monetary policy transmission, asset price channels, credit supply and demand for housing, and local market factors such as supply constraints and migration. Define key terms (quantitative easing, housing price index, mortgage spread) and give one short diagram to show the theoretical channel (e.g., QE → lower long rates → cheaper mortgages → higher demand → house prices). Use the five-year rule awareness and be explicit about the 2015–2020 time window in the research question so the examiner sees the scope from the start.

Plan and collect data systematically, prioritizing reliable secondary sources: ECB policy announcements and balance sheet data, Banco de España and INE house price indices for Madrid, regional property registries, mortgage rate series, construction permits, population and income for Madrid, and national macro variables (inflation, unemployment). If you choose primary data, keep it focused and small (a short survey of estate agents or a few structured interviews) and justify its limited role. Prepare a time-series panel at monthly or quarterly frequency if possible; document cleaning steps and include raw data in appendices. Pre-register your empirical strategy in the essay: consider difference-in-differences (comparing Madrid with similar Spanish cities), a VAR or ARDL for time-series responses, hedonic regressions for micro-level price determinants, or event-study windows around major QE announcements. Explain model choices, include formulas, check stationarity, control for confounders (local supply shocks, fiscal measures, tourism, COVID-19 from 2020), and run robustness checks (alternative indices, lag structures, placebo periods).

In analysis and writing, present clear tables and labeled graphs (price series, mortgage rates, QE intensity) and walk the reader through each result with mini-conclusions. Quantify effects (e.g., percentage price change per billion euros of ECB purchases) and interpret them using the theory introduced earlier; discuss heterogeneous impacts across neighbourhoods, housing types, or income brackets if data allow. Conclude by directly answering the research question, summarizing evidence strength, and evaluating limitations (data gaps, endogeneity, omitted variables). Cite all sources consistently, keep methodological detail in appendices (codes, robustness tables), and reflect honestly on reliability and scope so the examiner can follow and trust your argumentation.

Begin by anchoring your introduction around the research question: To what extent did the implementation of the Goods and Services Tax (GST) in India between 2017 and 2019 influence profit margins and price mark-ups in the organised textile manufacturing industry in Gujarat? Use the introduction to explain why Gujarat’s organised textile sector is a useful case (size, data availability, regional policy context) and to define key economic concepts such as profit margins, price mark-ups, costs of production, and tax incidence. State clearly your aim and scope (time period 2017–2019, organised textile manufacturing in Gujarat), and outline the theory you will apply—cost-plus pricing, market structure (oligopoly/monopolistic competition), tax pass-through, and short-run vs long-run effects. Briefly mention the data types you will use (firm financials, industry reports, GST tax rate schedules, input cost indices) and how these tie back to the research question so the examiner immediately sees focus and relevance. Design a methodology that mixes secondary and, where feasible, primary data. Collect secondary data from government sources (Ministry of Commerce/Industry, GST Council notifications, Directorate of Textiles), published company annual reports of organised textile firms in Gujarat, industry associations (e.g., Surat Textile Mills), and reputable databases (CMIE, IBEF). If possible, run short structured interviews or a questionnaire with managers or industry experts to validate mechanisms of tax pass-through and cost adjustments—justify the sample and ethical steps. Quantitatively, compile time-series firm-level or industry-level data on selling prices, input costs (cotton, dyed fabric, energy), gross margins and mark-ups before and after GST implementation. Use simple statistical tests (difference-in-differences if you can identify a control group, pre/post t-tests, and regression analysis controlling for demand shocks and input price volatility) and present calculations with clear formulas; visualise trends with labeled graphs and tables and place large datasets in appendices. In analysis and writing, link empirical results back to economic theory and the research question continuously: interpret changes in margins and mark-ups in light of tax incidence, competitive pressure, and supply chain adjustments. Discuss robustness (alternative explanations such as raw material price swings, exchange rates, or local policy changes), make mini-conclusions after key sections, and avoid overclaiming causality unless supported by your chosen methods. Conclude by summarising the extent to which GST influenced margins and mark-ups, outlining limitations of data/methods, and suggesting targeted extensions (longer post-GST window or firm-level panel data). Follow IB structure and citation rules precisely, include clear appendices, and ensure your writing remains concise, evidence-led and focused on answering the research question.

Start by framing your research question exactly as given and outline a clear, focused introduction that places it in context: briefly describe the 2018–2020 US tariff actions and Samsung Electronics’ role in the global smartphone market, define relevant economic concepts (tariffs as taxes, cost pass-through, supply-chain costs, price elasticity, market structure) and explain why the chosen time period is appropriate. In your introduction state the aim and the specific variables you will measure (e.g., changes in unit input costs, landed costs, and US retail smartphone prices) and include one or two simple diagrams to show expected effects (supply shifts, tax wedge, pass-through). Keep the research question visible on the title page and follow the prescribed EE structure—introduction, methodology, analysis, conclusion, bibliography, appendices—so assessors can easily follow your logic and mark against IB criteria.

Design a mixed-methods methodology that relies primarily on secondary quantitative data and, if feasible, targeted primary evidence (short email interview with a supply-chain manager or industry analyst). Identify precise, verifiable sources: Samsung annual/quarterly reports, filings (notes on cost of goods sold and freight), US Customs tariff schedules (HTS codes), US International Trade Commission, UN Comtrade or WITS for import flows, Bureau of Labor Statistics/PCE/CPI categories for smartphone prices, industry price trackers (Counterpoint, IDC), and reputable news coverage for chronology of trade actions. Collect data at monthly or quarterly frequency (2017–2021 recommended to show pre- and post-impacts), adjust for exchange rates and global input-price trends, and build datasets for (a) Samsung’s reported manufacturing/COGS metrics and (b) retail price series for comparable Samsung models in the US. Be explicit about source reliability, and place large tables and raw downloads in appendices.

For analysis, use economic theory to frame hypotheses (tariffs act like a tax raising importers’ marginal costs; pass-through depends on elasticity and market power) and apply empirical tools: descriptive trend charts, difference-in-differences comparing affected tariff lines or countries, regression analysis of retail prices on tariff exposure controlling for model, time, and global input cost indices, and simple cost-pass-through calculations. Present labeled graphs and sample calculations, interpret coefficients in economic terms, and draw mini-conclusions after each subsection. In the conclusion restate the research question, summarize evidence on how tariffs affected Samsung’s supply-chain costs and US retail prices, discuss limitations (data gaps, confounding events like FX or component shortages), and suggest modest extensions; document all sources meticulously in a bibliography and place supporting datasets and robustness checks in the appendices.
