Jie Lin RE: Week 1 Discussion COLLAPSE Top of Form 1. First of all, the production function shows the association between the amount of production and amount of output produced. And any adjustment in firm's marginal product of labor will lead to a change in production function. For instance, if the marginal production go up, the total amount of production will also increase. Moreover, the amount of marginal product of labor is the same as the wage rate, which means that the amount for labor demand is equal to the marginal product curve.

2. In an equilibrium market, the wage and the amount of labors will change according to the supply and demand in the market. And under the circumstance of equilibrium, firms will seek for profit maximization, which means they will hire workers until the wage is equivalent to the amount of marginal product. The marginal product of labor will equal to wage when supply and demand is in equilibrium. 3.

Under such circumstances, the wage rate will drop, as there will be a larger pool of labors for employer to select from. And the rents earned by owners of land and capital will likely increase, as there will be more people seeking for houses and accommodation in the market. 4. Education is type of capital in a sense that people will likely to get a job with higher salary if they got good education. Therefore, education can be seen as a type of human capital, as it consumes resources at one point that increases future productivity.

5. First of all, superstar has a good public image, as they are beloved by many people; Secondly, people want the best product from the best producer. And it is easier to see superstars in the music industry, as they can get large fan base easily through copy selling and putting out their works on music streaming services. As for dentistry, it is impossible for them to achieve a mass appeal. 6.

The discrimination might persist in a competitive market if a government allows its people to discriminate. For instance, the apartheid that happened in South Africa back in the 90s, which ensured white people's domination in society, politics, as well as economics.The black race at the time had no rights at all. Bottom of Form Qihui Ni RE: Week 1 Discussion COLLAPSE Top of Form 1. In economics, the production function relates the maximum amount of output can be produced from a given number of inputs (e.g. labor). When the number of workers increases, the marginal product of labor decreases, which means that the marginal product of labor highly relies on the production function and they have a negative relationship.

The value of the marginal product of labor equals marginal product of labor multiplied by the price of the product, so if the marginal product of labor increases, the value of the marginal product of labor must increase as well. A profit-maximizing company should always make employing decisions based on the value of the marginal product of labor and wage. There should be more labor when those two terms are the same level. 2. When the number of labor increases, the additional output produced is decreasing.

So it must change the equilibrium wage and the value of the marginal product by the same amount to allow the market of labor to be in equilibrium. When supply and demand are same, the value of marginal product of labor = wage. 3. When there are more and more available workers, the wage will decrease for sure, which will also increase the demand for additional labor. Besides, employers will demand more land to extend their company, so rent will go up in the later stage.

And for those workers, they need place to live, so the price level of rent will increase significantly. 4. Workers who have higher level of education qualifications can normally receive more salaries than those who don’t. The return for spending time on getting a better education qualification is being more productive in the future. 5.

First, consumers want to enjoy the product provided by the producer. Second, the cost of the product for all consumers is low, but still with a good and satisfied quality. For example, in dentistry, the cost of the product (service) is high, it is impossible to satisfy all consumers in the market, so there is no superstar in dentistry. On the other hand, in sports industry like basketball, the cost of watching NBA games is low no matter if you watch it on TV or online, so there are many superstars in the NBA. 6.

On one hand, in a competitive market, companies will try as best as they can to satisfy consumers preferences and tastes. For example, in movie industry in the U.S, if consumers prefer to see more white race actors than yellow race actors, movie producers will hire more white race actors than Asian actors. On the other hand, the capability also plays a key role in the competitive market, that’s why we have seen only see a few Asians in NBA. Bottom of Form SOCIAL ENGINEERING 6 As a hacker, the most successful use case is to target human error as a potential link to data breaches. Social engineering threats target psychological manipulation and human error and manipulate them to identify sensitive data (Krombholz et al., 2015).

It can convince users to breach security measures that an attacker can access. Poor cyber security culture is one of the best ways to launch an attack. Social engineering can be implemented in a variety of ways, including whaling, spearfishing, sight checking, and traditional fishing (Hartfield & Loukas, 2015). The reason I use phishing is that I can successfully use social networks, SMS, email and other forms of phishing to get information for personal purposes. The best way to do business is with microfinance.

Although security systems are complex, social engineering can guarantee successful fraud. The first thing to do is to manage employee phishing which could affect access to large amounts of data. A new employee is a good goal with a few safety precautions. For example, it checks the name and contact number of their name tags. After that, the next step is to develop an email equivalent to the main business email.

Sending a computer email wherever you need to install a newly needed patch update is an appropriate way to launch an attack (Krombholz et al., 2015). This email is called "Security Update for Windows 7 / 8.1, 8, and 10". The employee replied to a false e-mail indicating his real e-mail address. To get the data successfully, you need a cloned website. Another way is to search the names of employees working in the company's marketing department and access the latest project accounts.

Duplicate stolen invoices can be emailed to employees, requiring them to enter a password to unlock the document. Credentials will help you access your corporate network before you know it. This fishing method is effective because the higher the probability of obtaining information, the higher the number of targets. All details are recorded and stored on the cloning site. After a while, I sent an email to sign up for work services to improve my account security.

Look for reliable sources, like the new email management center. If they agree, they can submit login information to my database. The most important information is your username, password, personal identification number (PIN), personal details, credit card details and most recent transaction details. Targets can be listed through the antivirus you are using. It is important to use DNS spyware to ensure the success of e-phishing campaigns (Fernan et al., 2019).

This process helps determine the protection of the malware involved. The next step is to install antivirus software on the virtual machine. This is done before sending an email. Although it has the same version as the antivirus software used, it is not reliable. Common free antivirus software does not run VM antivirus software.

Therefore, the possibility should be checked before reaching the email recipient. In the process, I can buy real certificates for binary-dependent targets. After accessing the employee’s credentials, it is possible to log in as support staff. Changing the IP address to match the location of the micro-finance would be necessary to hinder digital forensics from tracking the remote computer. The next stage is to collect useful customer data, such as bank account details: emails, account numbers, names, residence, and contact details.

The hacking tries to minimize the capabilities of the real bank account owner to give commands. The website can be made to look legitimate and ask for more information regarding the credit card “authenticity check†(Heartfield & Loukas, 2015). Moreover, it should have a tricky link requesting them to download antivirus for their devices. The download of the actual virus will enable the stealing of more data from their computers. Phishing takes advantage of all weaknesses in both security and software.

However, it involves convincing, which must be included in drafting the emails. The email should have a deadline for clicking the links to the malicious website. They should also state the consequences of not taking the recommended action – this will lure them into logging in and revealing details. The stolen emails, credit card details, and account numbers can be useful for account takeover. For instance, an email address would help me act as the owner and gain access to the deposited cash.

It also facilitates changing of communication such as alerts, which helps to keep the victim unaware of account activities. Moreover, social engineering can help in making the account owners transfer the money themselves (Krombholz et al., 2015). I can pretend to be a senior bank officer with knowledge of the account information to gain trust. Telephone phishing can trick them into making security changes or authorizing a pending payment. Wire transfer is an interbank fund transfer that I can use to steal money from the users.

The authorization key can be sent by the customer to the fake website as they confuse it with password reset codes. Prior research of countries with lax banking regulations will be made, then connect with a trusted person in the country. The person should ensure that they target new tellers or non-experienced bank workers through social engineering. Such a person can be the weakest point to authorize a withdrawal since wire transfer takes several days to mature (Peng et al., 2016). Another way of making huge withdrawals include bribing some corrupt officers.

If the victims realize they can cancel the transaction, and the micro-finance will incur losses. To conclude, social engineering is conducted by tricking individuals into sharing details willingly. This data can be used to commit social engineering fraud, wire transfer, account take over, and other fraudulent activities. Targeting micro-finance employees provides the most vulnerable point of achieving information. Moreover, phishing through sending malicious emails impersonating corporate leaders can trick employees into sharing their login data.

The access of accounts can help to steal bank details, credit card information, PINs, passwords, and other information. More social engineering through phone phishing can be used to convince clients and workers. References Farnan, O., Wright, J., & Darer, A. (2019, May).

Understanding Production Functions, Labor Economics, and Market Dynamics

Introduction

In economics, the production function represents the relationship between input factors and the output produced by a firm. The primary inputs in production usually involve labor, capital, and land. Understanding production functions allows firms to maximize output efficiency and assess labor demand. Consequently, analyzing how equilibrium wages are determined, the effects of labor supply changes, and the impact of education on labor markets forms the backbone of economic discussions in terms of human capital and market reactions.

The Production Function and Marginal Product of Labor

The production function indicates the maximum amount of output that can be produced with given input levels (Koutsoyiannis, 1977). For instance, as observed in both Jie Lin's and Qihui Ni's postings, an increase in labor typically leads to diminishing marginal returns. This means that while each additional worker can add to total output, the incremental output contributed by each additional worker (the marginal product of labor) tends to decrease (Mankiw, 2016). The equilibrium wage in a competitive labor market should, therefore, equal the value of the marginal product of labor, which can be defined mathematically as the product of the marginal product of labor and the price of the produced good.
This relationship between wage and marginal product reinforces the principle that employers will endeavor to hire workers until the value of the marginal product is equal to the wage paid to those workers (Borjas, 2016). If marginal productivity rises, firms will be incentivized to increase hiring, leading to upward pressure on wages.

Market Equilibrium and Wage Dynamics

In market equilibrium, changes in labor supply will influence wage levels. An increase in labor availability, often due to a larger pool of job seekers, generally results in lower wage rates, mainly because employers have more choices among potential hires. Conversely, in markets where demand for labor outstrips supply, wages will likely increase as firms compete for a smaller workforce (Kim & Kim, 2019).
Thus, in a scenario where there's a significant influx of labor into the market, employers may find that they have an extended pool of candidates, which dilutes competition for individual jobs. In turn, as wages fall, firms may seek to capitalize on lower labor costs, leading to increased rents for owners of land and capital as demand for housing and office space rises (Stiglitz, 2014).

Education as Human Capital

Education is broadly regarded as a form of human capital, representing the skills and knowledge that enhance a worker's productivity. Higher education typically allows individuals to command higher wages due to increased productivity and capability (Becker, 1993). Consequently, investments in education can be viewed as both private and public economic strategies for enhancing overall productivity and economic growth (Psacharopoulos & Patrinos, 2018).
The potential returns on such investment manifest in various labor market outcomes. Workers with higher qualifications often experience lower unemployment rates and better job stability and satisfaction. For example, a skilled labor force can attract firms seeking innovative solutions, thereby enhancing regional economic development.

The Phenomenon of Superstars in Certain Markets

Jie Lin and Qihui Ni also discussed the emergence of "superstars" in specific industries, showing how visibility and demand can lead to disproportionate rewards for top talent. In entertainment, for example, the accessibility of digital platforms allows a few individuals to capture large market shares due to fan engagement and wide audience reach (Rosen, 1981). Contrarily, professions such as dentistry lack the widespread appeal inherent to entertainers, leading to a scarcity of "superstars" in that field.
This disparity highlights the role of market structures in talent distribution. In industries where consumers can easily compare and access offerings (such as music and sports), distinct talent can rise to prominence efficiently (Binken & Stremersch, 2008). This phenomenon often leads to unequal income distribution, fueling broader economic discussions on policy interventions to mitigate inequality.

Discrimination and Market Dynamics

Discrimination can disrupt market equilibria, as illustrated by Jie Lin's reference to apartheid in South Africa, which led to economic disparities along racial lines (Marois, 2019). Discrimination in hiring can persist if the market mechanisms do not eliminate biases, thus perpetuating inequities even within competitive contexts. Employers may prioritize candidates based on race or gender rather than merit, leading to suboptimal outcomes for firms and overall economy productivity (Kahn, 2014).
In a truly competitive market, market forces would ideally promote equality of opportunity, encouraging firms to hire the best talent irrespective of background. Nevertheless, when systemic inequalities prevail, the impact of discrimination can undermine productivity and economic growth, pointing to the need for policies that foster inclusivity (Bertrand & Mullainathan, 2004).

Conclusion

In summary, understanding the interplay of production functions, labor economics, and market dynamics provides invaluable insights into how economies function. From the relationships depicted in production functions to the nuanced effects of education and discrimination, these factors collectively shape labor markets. As we move forward, it remains essential to consider how policies can optimize labor market outcomes and ensure sustainable economic growth.
