 Iva Aleksic Fiscal policy plays an important role in shaping economies. Governments use taxation, public spending, and borrowing to manage growth, control inflation, and respond to economic shocks. However, when a large economy like the United States makes big fiscal changes, the effects extend far beyond its borders. A well-designed policy can fuel economic expansion, while a poorly managed one can lead to rising deficits, inflation, or financial instability. One of the most important economic principles behind fiscal policy is the multiplier effect. The fiscal multiplier measures how much total economic output (GDP) changes in response to an increase or decrease in government spending or taxation. It helps policymakers predict the effectiveness of fiscal policy. The higher multiplier effect the higher GDP growth, because it means that each dollar of government spending or tax cuts creates a larger overall increase in economic output.  MPC (Marginal Propensity to Consume) ...

 Georgios Xoxakos Price Elasticity of Demand (PED) is a measure of how responsive demand is to a change of price. The movie industry has seen drastic shifts in the behavior of consumers. The cost of movie tickets and streaming subscription fees directly influences consumer choices. PED helps us understand how demand for these services changes when prices fluctuate, whether in theaters or on digital platforms. In movie theaters, PED plays a crucial role in a film’s success, as theatrical releases are the first opportunity for audiences to watch new movies. The demand for tickets can be either elastic or inelastic, depending on the type of film. Blockbuster premieres, such as  Marvel’s Avengers  or  Avatar , typically have inelastic demand because fans are willing to pay higher prices to experience them on the big screen. Similarly, movies featuring a well-known cast or a renowned director often exhibit inelastic demand as well. For example,  Pulp Fiction , star...

 Iva Aleksic In economics, different market structures determine how firms operate, set prices, and interact with consumers. A monopoly is a market structure in which a single firm is the sole seller of a product with no close substitutes. However, in today’s economy, monopolies are not always built through innovation or efficiency, they can be bought. The key difference between traditional monopolies and modern ones lies in how they establish dominance. In the past, firms like Standard Oil and AT&T built monopolies by controlling supply chains and lowering costs to outcompete rivals. Today, however, monopolistic firms often achieve dominance through external growth. Instead of competing in an open market, they eliminate potential rivals by purchasing them, reducing competition and strengthening their dominance. This raises a crucial economic question: Are monopolies today truly gaining power through market superiority, or are they simply acquiring their way to the top?   ...

  Tamanna Suri (Edited by Sevin Karabulut) Despite UK regulations limiting the amount of nicotine in vapes, consumption of this persists due to smuggling from countries with looser laws. This blog will explore the negative externalities of vaping; it will discuss its impact on public health and NHS spending, thus government spending and the opportunity costs associated with this. Moreover, the blog will consider the UK’s rising national debt to discuss whether the negative externalities justify stricter governance of vaping.   Before delving into the case study, it is important to understand what negative externalities are and their impact on society. Negative externalities refer to the costs on third parties due to the actions of producers and consumers. This blog will focus on the negative externalities of the consumption of vapes in the UK: The graph above demonstrates the negative externalities of vaping consumption.  Here, the marginal private benefit (MPB) e...

Tianrui Ling This blog explores how oligopolistic markets operate through game theory and Nash equilibrium, using the Chinese telecommunications industry as a case study. We will also discuss game theory's application in environmental sustainability and its alignment with oligopoly theories, highlighting the balance between cooperation and competition for optimal outcomes. Exploring Oligopoly with Game Theory and Nash Equilibrium Oligopoly refers to a market structure dominated by a few large companies that have a great influence on prices and output. Companies must take into account the behaviour of their competitors, creating tension between cooperation and self-interest. While cooperative behaviour can lead to higher prices, the lure of individual profit often leads to increased production and lower prices. Game theory analyses strategic interactions in oligopolistic markets. Companies' decisions depend on their own strategies and those of their competitors. In such markets,...
