  Introduction South America is entering a pivotal phase in its digital and economic transformation. With countries like Brazil, Mexico, and Argentina investing heavily in data infrastructure, analytics, and digital governance, the region presents both challenges and opportunities for professionals working in Business Intelligence (BI), Data Analysis, and IT Project Management. This post explores the key data trends shaping South America in 2025, backed by insights from the World Bank, OECD, and Statista. It’s designed for analysts, project managers, and decision-makers who want to understand the region’s evolving landscape and how to position themselves for impact. 1. Economic Outlook: A Region in Transition According to the World Bank’s Global Economic Prospects 2025 , Latin America is expected to experience slower growth compared to global averages, with GDP expansion constrained by trade tensions and policy uncertainty. Brazil and Mexico remain the largest economies, with proj...

Friedrich August von Hayek (1899-1992) was an Austrian-British economist, political philosopher, Nobel laureate and—above all—a relentless defender of individual liberty. His critique of socialism is more than an economic argument; it is a warning that every attempt to “design” society from above chips away at the very freedom that makes prosperity possible. BACKGROUND IN BRIEF • Born in Vienna into an academic family; fought in WWI, then studied law and economics at the University of Vienna. • Early career in the “Austrian School of Economics” alongside Ludwig von Mises. • 1930s: sparred with John Maynard Keynes over business-cycle theory at the London School of Economics. • Post-WWII: shifted toward political philosophy, writing The Road to Serfdom (1944) and The Constitution of Liberty (1960). • 1974: shared the Nobel Prize in Economics with Gunnar Myrdal for work on the interdependence of economic and institutional phenomena. THE THREE IDEAS THAT MADE HAYEK IMMORTAL 2.1 THE KNOWLED...

 Today’s spotlight is on John Maynard Keynes , the British economist who revolutionized our understanding of national economies. Through his groundbreaking book, The General Theory of Employment, Interest and Money (1936), Keynes laid the foundation for modern macroeconomics . The Problem: Great Depression During the Great Depression , unemployment soared and demand collapsed. Classical economists believed markets would self-correct — but they didn’t. Keynes argued that this crisis called for a new way of thinking . Keynesian Revolution Keynes rejected the idea that supply creates its own demand (“Say’s Law”). Instead, he proposed that aggregate demand — total spending in the economy — determines output and employment. If people aren’t spending, businesses don’t produce. If businesses don’t produce, workers lose jobs. The Role of Government To break the vicious cycle of recession, Keynes recommended: Public spending to stimulate demand Monetary policies to low...

 Turning Raw Numbers into Strategic Decisions Executive Summary Data is everywhere, yet only a tiny fraction of small and medium enterprises (SMEs) transform it into action. This long-form guide shows how to build an end-to-end storytelling workflow that blends business intelligence (BI), artificial intelligence (AI) and human insight. You will see fresh survey data from 87 European SMEs, two deep-dive case studies, a reusable framework, and a set of ready-to-implement best practices. By the end, you will know exactly how to move from scattered spreadsheets to persuasive narratives that change minds, win budgets, and boost revenue. Why Data Storytelling Matters for SMEs Most SMEs operate on razor-thin margins and compete against both local rivals and global platforms. In that environment, decisions must be fast, defensible, and shared across non-technical teams. Raw dashboards rarely achieve this. Storytelling adds structure and emotion to analytics, making insights stick in memory...

 Welcome back to the blog! Today we explore the fascinating work of Léon Walras , a French economist and mathematician who transformed economics by giving it a solid mathematical foundation. He is widely regarded as the father of general equilibrium theory — a model that explains how multiple markets interact and reach equilibrium simultaneously. Who Was Léon Walras? Walras was born in France and originally trained as an engineer. But he later shifted to economics, where his mathematical skills helped him approach economic problems in a completely new way. He believed that economics should be treated like physics — based on precise laws and formulas. The Theory of General Equilibrium Before Walras, economists studied markets mostly in isolation. Walras asked a bigger question: What happens when all markets in an economy — for goods, labor, capital — interact at the same time ? He built a model in which all supply and demand curves across different markets are interrela...

  Welcome back to the blog! Today we explore the life and legacy of Alfred Marshall (1842–1924) , the British economist who laid the foundations of modern microeconomics . His landmark book, Principles of Economics (1890), introduced core concepts like supply and demand , elasticity , and market equilibrium — ideas that continue to shape how we understand economics today. Who Was Alfred Marshall? Alfred Marshall was a professor at the University of Cambridge and a key figure in the development of neoclassical economics . He believed economics should be rigorous, mathematical, and practical , focusing on real-world issues like prices, wages, and consumer behavior. Marshall also emphasized that economics is ultimately about improving human well-being. Key Contributions 1. Supply and Demand Analysis Marshall was the first to clearly present supply and demand as intersecting curves on a graph. He showed how prices are determined by both what consumers are willing to pay (dem...
